Mark Wright has kept 'Coronation Street' favourite Tina McIntyre's killer a secret.
The reality TV star, who is engaged to actress Michelle Keegan, was on set for his fiancée's final scenes - in which Tina plunges to her death after being pushed by a mystery assailant - and is one of the few people who knows the top secret soap spoiler.
Michelle revealed to ITV's 'This Morning': "I know who the killer is. We did film different endings, but the longer version [we filmed] was who did it."
"I haven't said anything to anyone. Does Mark know? Well, he was there when we filmed it. But to be fair, he hasn't told anyone. He's been really good!"
Four suspects will be in the frame for Tina's murder and viewers won't have to wait long to find out who kills her, as their identity will be revealed in next Tuesday's (27.05.14) episode.
The potential murderers include Peter Barlow (Chris Gascoyne), Carla Barlow (Alison King), Tracy Barlow (Kate Ford) and Rob Donovan (Marc Baylis).
Meanwhile, Michelle, 26, is moving to Essex to live with Mark, 27, but she admits they still aren't ready to move in to their new house.
She said: "I've not moved down yet, he keeps saying two weeks, but that was three months ago! It's taking ages for the house to go through - but yes, I am moving down."

Coronation Street's Jennie McAlpine is pregnant.
The 30-year-old actress - who plays Fiz Stape in the ITV soap - is expecting her first child with restaurant manager Chris Farr.
Jennie shared the happy news on Twitter earlier today (21.05.14), writing: "We have some news to share. Chris and I are expecting an addition to our family. Very happy x (sic)"
Many of Jennie's 'Corrie' co-stars shared in her baby joy, with departing star Michelle Keegan - who plays Tina McIntyre - leading the well wishes.
She tweeted: "@jenniemcalpine arghhhhhhhhhhhhhh JEN!!!!!! SO SO excited for u!! Congratulations! Amazing news!!!!!! Xxx (sic)"
Fellow 'Corrie' parent Jack P. Shepherd (David Platt), who has two children with fiancée Lauren Shippey, added: "@jenniemcalpine knew it! Well done! X (sic)"
Soap newcomer Tisha Drew Merry (Steph Britton) wrote: "@jenniemcalpine yeyyyyyyy!!!! Congrats jen!! Xx (sic)"
Jennie has been dating Chris since 2005 and the couple even opened a restaurant together in 2012.
The fiery-haired actress has been at the centre of a dramatic plot in 'Corrie' as Fiz and Tyrone Dobbs (Alan Halsall) recently discovered that Maria Connor (Samia Ghadie) is the person behind a series of malicious texts, which they feared were from Tyrone's abusive ex Kirsty Soames.

Matt Smith has vowed to return to 'Doctor Who'.
The 31-year-old actor bowed out of his role as the titular Time Lord in last year's Christmas special, but he can't wait for the next special anniversary episode so he can reprise his role as the Eleventh Doctor.
Speaking at this year's Calgary Expo fan convention, he reportedly said: "I'm just waiting for the next anniversary. I spoke to Steven [Moffat, executive producer] the other day and said, 'What's the quickest one we can do?' "
Matt hopes to celebrate the next anniversary of the show by bringing back the past 11 Doctors to join new incarnation, Peter Capaldi.
He added: "I love the idea of other Doctors coming back. Also that gives me the opportunity to come back, which I totally will, by the way!"
All 12 Doctors were seen together in last November's 50th anniversary special of 'Doctor Who', which was titled 'The Day of the Doctor'.
The new series of the BBC sci-fi drama will begin on BBC One in the autumn, with Peter being joined by Jenna Coleman as his companion.
Guest stars in the new episodes include comedian Frank Skinner and 'Line of Duty' actress Keeley Hawes.

Quincy Jones has blasted the new Michael Jackson album 'Xscape'.
The legendary producer - who masterminded some of the late singer's biggest hits - thinks the posthumous recording was only released to "make money".
He said: "It's about money. They're trying to make money. And I understand it. Everybody's after money, the estate, the lawyers. It's about money.
Quincy admitted it "bothers" him to see so much of the 'Thriller' star's previously-unreleased music being made public but has learned to accept it has nothing to do with him.
Asked if he was bothered by the recordings, he told Jian Ghomeshi's 'Q' talk show on CBC Radio: "Yeah, but it's not my business anymore. They're not our business."
Quincy's comments come months after he launched a $10 million breach-of-contract lawsuit in relation to the recordings released after the 'Billie Jean' stars death in June 2009.
He alleged master recordings he had worked on were wrongfully edited and remixed so as to deprive him of back-end profit participation.
He also claimed he had been denied credit for his work and that MJJ Productions and Sony Music have entered into deals taking profits that should have been included in the calculation of royalties.

Alana Haim is "not afraid" to admit she was a huge fan of the Spice Girls.
The 22-year-old musician, who is in girl rock band Haim with sisters Este and Danielle, is known as Baby Haim because she loved Emma Bunton from the 90s pop group and is the youngest in her family.
She said: "The reason why I'm Baby Haim is because I was the biggest Spice Girls fan growing up. I always wanted to be Baby Spice growing up, but I didn't have blonde hair. When I was 16, one of my friends was like, 'You're Baby Haim, you're the baby of the family!' and I was like, 'Oh my God, dream come true, I can be like Baby Spice'. They were the first band I was a fanatic [for].
"It was Spice Girls and Destiny's Child, my two go-to bands. I had all the dolls, all the weird lollipops, all the movies. I was a f***ing huge Spice Girls fan, and I am not afraid to say it."
The Spice Girls - also made up of Mel C, Mel B, Victoria Beckham and Geri Halliwell - were known for their choreographed dance routines, and Haim have decided to show off their moves in the video for their track 'If I Could Change Your Mind'.
Alana added to TIME magazine: "[Veteran choreographer] Fatima [Robinson] definitely f**king whipped our asses into shape for sure. "We only had three days to choreograph it and perform.
"We really wanted to be actual dancers. I mean, we're not actual dancers ... we quickly realised that after day one."

Channing Tatum says it gets "zany and crazy" at strippers' conventions.
The 34-year-old actor is currently working on a sequel to 'Magic Mike' which was loosely based on his experience as an 18-year-old stripper in Tampa, Florida.
'Magic Mike 2' is inspired by two "absolutely insane" strippers' conventions he attended, one of which was in Raleigh, North Carolina where they danced for 3,000 women.
Talking to US GQ magazine, he said: "The women would come from miles and miles around.
"Then you lock the doors and you say all bets are off. It gets zany and crazy, and it's a wild ride. It's an incubator for insanity. It doesn't matter almost what you do onstage. I don't want to put anything in black and white on a page, but if you've been to one, you know how crazy it gets, and now pour kerosene on that. You've seen 'Magic Mike' -- now multiply that. Mob mentality. It's just exponentially crazier. I thought it was absolutely insane."
Tatum has tried to convince Steven Soderbergh - who directed the original - to helm the follow-up but he's not going to do a u-turn on his recent retirement from movie directing and instead his longtime producing partner, Greg Jacobs, will take on the project.
He added: "It's super complicated, in my opinion, why he wanted to stop doing film. I lobbied probably harder than anybody else--we had many, many nights of heated debate. I was, 'I don't f***ing get it! Why?' And he's like, 'I don't need it.' "

Star Wars' fans can win a chance to appear in Episode VII.
Director J.J. Abrams is backing Star Wars: Force for Change, a campaign which will raise funds and awareness for the United Nations Children's Fund's (UNICEF) Innovation Labs and fans can contribute to the cause between May 21 - July 18 through Omaze.com/StarWars.
For each $10 contribution made eligible participants will be entered into the draw for the incredible prize which will also include airfare and accommodation in London, behind-the-scenes access on the closed set and the opportunity to meet the A-List cast.
Abrams explained: "The 'Star Wars' fans are some of the most passionate and committed folks around the globe.
"We're thrilled to offer a chance to come behind the scenes as our VIP guests and be in Star Wars: Episode VII."
Star Wars: Force for Change aims to help the world's most vulnerable children and create sustainable solutions to issues including nutrition, water, health, and education.
Meanwhile, 'Star Wars: Episode VII' will see former stars Harrison Ford, Mark Hamill and Carrie Fisher return alongside newcomers John Boyega, Daisy Ridley, Andy Serkis, Oscar Isaac, Domhnall Gleeson and Max von Sydow.
Filming began in Abu Dhabi last week and is then expected to continue at Pinewood Studios in Buckinghamshire, England.
The movie, which has a screenplay written by the director and Lawrence Kasban, opens worldwide on December 18, 2015.

Simon Kinberg says 'X-Men: Apocalypse' will be even "bigger" than the franchise's seven previous films.
The producer behind 'X-Men: First Class' (2011) and 'X-Men: Days of Future Past' (2014) - the latest in the Marvel comic book-based series - believes the next installment of the movie franchise will top all previous efforts.
He told Collider.com: "Apocalypse, because of the nature of apocalypse and all of the roll and emeric style destruction that comes with it, felt like it was a bigger movie and felt like it was an opportunity to follow our main 'First Class' characters in the next step of their lives.
"It'll pick up after Days of Future Past, in the past, it'll be a few years later."
Although the 40-year-old screenwriter and producer has no doubts about the movie's potential for success he admitted his team struggled to come up with a story worthy of following 'X-Men: Days of Future Past'.
He said: "We're at the beginning of the scripting phase. We've already been working on the story since we were shooting 'X-Men: Days of Future Past' and we were on set, Brian [Singer] and the other producers Lauren and Hotch Parker we all talked about what the next chapter of the X-Men would be.
"It's a hard movie to follow because you're never really going to get all the cast back together. The event of 'Days of Future Past' is almost like our 'Avengers'. So it's, how do we take the story forward and in some ways build on the scope and scale of the franchise with mass characters."
'X-Men: Apocalypse' - starring Jennifer Lawrence, Michael Fassbender, Nicholas Hoult and James McAvoy - will be directed by Bryan Singer and although plot details are yet to be released the film is set to hit cinemas in 2016.

James McAvoy and Nicholas Hoult played with BB Guns on the set of 'X-Men: Days of Future Past'.
The 35-year-old actor and his co-star - who is dating Jennifer Lawrence - had a "lot of fun" with the popular children's toys when they had hours to spare in between takes.
Speaking on US Chat show 'The View', James explained: "There was a lot of fooling around - you know, not that kind of fooling around.
"There was weirdly a lot of fighting. We had a lot of BB Guns and things like that. Myself and Nick Hoult, who plays Beast, went to a big Canadian superstore and bought those BB Guns ...
"You know what it's like when you've got five - six hours between special effects shots and things like that. You can sit around and get depressed or you can try and shoot each other. It was fairly intense, it was a lot of fun. "
While he had a fun on set, it seems doing promo can be just as entertaining.
He recently revealed he almost crashed a helicopter on his way to Sao Paulo after the pilot invited him to take control of the aircraft
The hunk said: "I looked at him and thought he was joking. And then he took his hands off the joystick...
"I did think the pilot was insane but I like that kind of crazy. So I was holding the joystick and was thinking this is doable, this was fine and then the slightest movement and then it would go shwwm......I think the pilot s**t himself and took back the controls. "

Madonna's father urged her to stop simulating sex acts in photoshoots and music videos.
The 55-year-old pop star admits her dad, Tony Ciccone, expressed his dislike for her provocative image and asked if it was necessary for her to be so sexual in public.
She told America's V Magazine: "I would always say, 'Dad, I'm an artist, I have to express myself. You don't understand ... He's like, 'Do you have to simulate masturbation on the bed? Do you have to?' Yes, dad, I do."
The 'Hung Up' star also joked her dad has "finally" learned to accept her raunchy image.
She added: "I think he's finally come to terms with it. It's only taken 30 years."
The Queen of Pop appears on the cover of the magazine's summer 2014 issue and accompanying racy photoshoot with 'Birthday' hitmaker Katy Perry.
One image shows Madonna on all fours, while another features Katy straddling the 'Material Girl' singer, with both pop stars in flesh-baring leather outfits.
Katy also told the publication she is yet to start pushing the boundaries like singer Miley Cyrus, who posed naked on a wrecking ball for her hit song, but hasn't ruled it out.
The star said: "I haven't gone that far yet," adding to Madonna, "but maybe under your great mentorship I might reach that point."
Other sexy images in the magazine spread show Katy, 29, holding a rope tying together Madonna's hands, while the megastar is laid out on a leather sofa.

Jay Z and Beyonce will earn $2 million for performing at Kanye West and Kim Kardashian's wedding.
The couple are reportedly in final negotiations with E! - who produce 'Keeping Up with the Kardashians' and are believed to be part-funding the nuptials - about giving a "short set" at the celebrations.
A source said: "Jay Z and Beyonce will also perform at the wedding, as long as their last-minute negotiations with E! work out.
"The two have demanded $2 million for a short show."
Kim is said to have splashed out another $2 million on one wedding gown - and she hasn't decided yet whether to wear it.
The brunette beauty reportedly asked Alexander McQueen's Sarah Burton - who designed the gown the then-Kate Middleton wore to marry Britain's Prince William in 2010 - to create one of the outfits she is considering wearing on the big day, but has another two possibles to choose from.
A source said: "She has called on Sarah Burton to design one of her options. Kim wants the low-cut v-neck look that Kate had, but much lower, and she wants her gown to be tight fitting to show off her svelte figure.
"Her gown is estimated to cost $2 million. And no one will see the gown until she walks down the aisle. There are three gowns that were made just for her and she hasn't even decided yet between them."
While E! are footing part of the bill, the couple - who have 11-month-old daughter North together - are also splashing out another $7 million for expenses including catering.
A source told RadarOnline.com: "The two have planned a rehearsal dinner that costs an estimated $650,000.
"And they are paying for a lot of that. Chefs from around the world are being flown in to prepare dinner for the rehearsal night and the reception dinner after the wedding."
"High-end and extensive security is costing $3 million, flowers are $1 million and food is about $2,000 a plate."
As well as Beyonce and Jay Z - who were initially reported to be snubbing the ceremony because they didn't want to be filmed - Lana Del Rey is also believed to be performing for the guests as they quaff $6,000-per-bottle champagne.
The celebrations will end with a $200,000 fireworks display.

Michael Lohan allegedly scammed a young businessman into two fake business deals.
The showbiz patriarch has been accused of using his famous daughter Lindsay Lohan as an incentive for budding entrepreneur Jason Squatriglia, 20, to invest $50,000 in two bogus investments, a cleaning product and a reality TV show called 'Racing With the Stars'.
The youngster - who made $200,000 as a teen selling rare coins on eBay - claims he was taken under Michael's wing with the promise of making some serious cash, but things soon turned sour.
Jason told the New York Post: "He promised me the world. He took me under his wing. At that point, I knew I was going to invest money with him, and I felt comfortable with him.
"While in LA, he kind of used Lindsay as bait. It captivated my attention. He tried to get me to invest more, as if to say, 'Look at my daughter. She's a big movie star.' "
Michael reportedly wooed impressionable Jason by letting him drive his Maserati and wear his Rolex watch, as well as landing him an exclusive party invite to David Hasselhoff's house.
The pair set up production company JaLo Ventures LLC with the intention of making a reality show about stars racing sportscars around Florida, and Michael also encouraged Jason to invest his dosh into a product called Vital Oxide.
Despite Jason's parents begging him not to enter into business with Michael, who spent three years in jail for insider trading, the eager teen sent his mentor $50,000 on October 22, 2012, but has never seen his investment returned.
Upon hearing Jason's claims Michael still texts him asking for more money, Michael scoffed: "This kid is twisting everything."
Michael - who calls Jason by the nickname 'Junior' - claims the show failed to be green lit because they couldn't find sponsors and says there has been no cash made on the cleaning product yet due to a delay in shooting an advert.
