Former 'X Factor' stars Tamera Foster and Sam Callahan have split up.
The couple began dating after meeting on the show last year but 17-year-old Tamera is now said to have called it quits so she can focus on her music career.
A source said: "Tamera had strong feelings for Sam, but she is also very ambitious.
"It wasn't her intention to hurt him, but she knew it was time to move on.
"Sam is moving on with his career and is still very ambitious so it just wasn't going to work."
Despite coming in fifth place in the 2013 series of the ITV talent show - which was won by Sam Bailey - Tamera was offered a contract with Simon Cowell's record company Syco, while her 20-year-old boyfriend was left to pave his own way in the music industry.
And although Tamera stood by her beau after it was revealed he'd been sending flirty messages to a glamour model last year, she's now said to have been persuaded to end the relationship to distance herself from her time on the show as Syco attempt to launch her career.
The brunette beauty recently teased fans with news of her upcoming music on Twitter.
She wrote: "messege to all of my fans ! Thank you for being so patient, I'm taking my time so I can give you the best ! I won't let you down 2015 (sic)."

Amy Adams says her "spiritual animal" is a dog.
The 'American Hustle' star whips herself into a frenzy of eager anticipation when she meets new people on sets just like a puppy.
She said: "When I was younger, I was just so hyper and friendly to everybody. And still now, when I come on set, I'm like a golden retriever at a dog park, because I'm just so happy to be around people and eager to please."
Despite being nominated for five Oscars, the 40-year-old star claims she was fired from 'Grosse Pointe' in 2000 because she "probably sucked."
She said: "There was a TV show called 'Grosse Pointe' that I was fired from. I probably sucked. I never got a straight answer. It was my second year in LA, and I got hired for two pilots and got fired from both of them. The produced called me and said, 'It's not working.'
"And I was like, I know, I could tell.'"
The 'Fighter' star says was a "mess" when she first moved to Hollywood from Minnesota when she was 24 and almost quit acting as a result of the "pressure".
She told Britain's Vogue magazine: "I was able to do everything from day player to guest star to small parts in movies, and it really, to this day, give me perspective, but going through it was painful, to say the least. I felt a lot of pressure, but I just wasn't able to get there in the audition room. Or even in meetings.
"My squirreliness would come out and people wouldn't feel confident. I've always been someone who had, like, a spirit of perseverance, but I actually almost quit because I was starting to not like who I was.
"My lawyer called me up after I was fired from the two shows and said, 'Just to even get two shows in pilot season is amazing. So you're doing something right.' I thank him all the time for that call."

Susan Boyle is dating an American doctor.
The 53-year-old star met the medic - whom she describes as the "perfect gentlemen" - at her hotel during the Florida leg of her US tour and, after enjoying a romantic lunch date, she's now hoping he'll come over to the UK to visit her in her native Scotland.
She said: "It's very early days so we'll see what happens. I hope he comes over.
"I don't want to say any more about who he is right now as that would be unfair on him. All I'll say is we are around the same age and he was a very nice guy."
The 'Britain's Got Talent' runner up - who previously confessed to having never been kissed before - opened up about the date she enjoyed with her new man, revealing it ended with a "peck on the cheek".
Susan told The Sun newspaper: "He wasn't a fan but he knew who I was.
"He invited me out for lunch the next day. We had a nice chat and spoke about lots of things including our careers.
"He was the perfect gentleman and even paid the bill.
"Afterwards we exchanged details. When we said goodbye he gave me a peck on the cheek.
"He wants to come over and see me. I don't know my tour dates yet though so nothing has been set in stone."
And Susan is hoping to impress her new beau with a new skill the next time she sees him, admitting she's been taking tap dancing lessons "just for fun".

Khloe Kardashian's family have reportedly warned her to dump French Montana.
The 'Keeping Up with the Kardashians' star's famous family are said to have had a heart-to-heart talk with her earlier this week after becoming suspicious of her on-off beau.
The Kardashians - including Khloe's sister Kim Kardashian West and mum Kris Jenner - believe French has been unfaithful to Khloe and think he even used Kim as a cover for his infidelity, gossip site TMZ.com reports.
During a recent trip to Dubai, French is believed to have been hooking up with an attractive woman in between bumping into Kim long enough to have his picture taken with her in order to trick Khloe into thinking he was simply hanging out with her sister and other pals.
However, the 'Ain't Worried About Nothin' rapper's plan is said to have unravelled when Kim arrived back in the US and told Khloe she'd spent very little time with French, leading to the family becoming convinced he used Kim to deceive her own sister.
Meanwhile, French recently claimed he would refuse to sign a prenuptial agreement if he were to marry Khloe after it took him two years and $2 million to finalise his divorce from ex-wife Nadeen Kharpouch.
He said: "I just settled a divorce and gave somebody money."
The 30-year-old star added that there would be "no prenups" if he and Khloe decide to tie the knot.

Kanye West reportedly spent Thanksgiving in Paris.
The 'Black Skinhead' rapper was believed to have attended a family dinner hosted by his wife Kim Kardashian West's sister Khloe Kardashian but it's now been revealed he decided to mark the occasion without the help of his family.
Kanye, 37, left his wife and 17-month-old daughter North in the US while he jetted off to the French city to dine at Ralph Lauren's restaurant with two male friends, the New York Post newspaper's PageSix reports.
However, Kim seemed to be unfazed by her husband's decision to skip her family meal, as she took to Twitter to reveal what she was thankful for on the American holiday.
She wrote: "Happy Thanksgiving! I'm so thankful to have spent the day with my whole family over at Khloes house today! Khloe cooked so much yummy food! (sic)."
The 34-year-old beauty also hinted she has no plans to take on the role of a traditional housewife by hosting her own Thanksgiving dinner in the future, claiming Khloe, 30, will be doing it every year from now on.
She added: "Thank you for start a new tradition Khlo! Thanksgiving at Koko's (sic)."
And while Kanye is reported to have missed out on the celebrations, Kim and Khloe's pregnant sister Kourtney Kardashian, 35, and her partner Scott Disick and their children Mason, four, and Penelope, two, and brother Rob Kardashian were among the guests there to indulge in turkey, pumpkin pie and other festive treats.

Colin Firth got tired of waiting to be asked to play James Bond.
The 54-year-old actor portrays a suave secret agent in 'Kingsman: The Secret Service' and while he was attracted to the role because it was similar to the shows and movies he loved in the 1960s, he joked he took the part because he had accepted he wasn't going to be offered the role of the iconic spy who is currently played by Daniel Craig.
He said: "I think to a very large extent, in terms of style, the character of the spy movies I fell in love with has its roots in the 60s. It's 'The Man from UNCLE', it's the 'Harry Palmer' films, it's John Steed's 'Avengers' and those early Bond films.
"It's the guy in the suit who seems slick and cool and capable and is very, very contained but you cross him at your peril. He'll get you with the umbrella or a slick move or a gadget or something. It was all that.
"I'd been waiting for the offer on Bond for long enough, but it was [director] Matthew Vaughn who decided that it was a good combination."
The 'Bridget Jones' Diary' star admits the director only approached him because he felt he was such a surprising choice for the part.
He admitted to SFX magazine: "Matthew limes to take your presumptions about people and then flip them on their head, so he came to me and said, 'I think you're the last person on Earth anybody would expect to kick anyone's ass so I think it would be a big surprise. But I would like you to do it, so are you up for it?"

Taylor Swift works out to improve her "endurance" on stage.
The svelte blonde beauty has admitted to disliking her punishing spin classes at the gym but explained that they have helped her deal with her crazy dance routines.
The 'Shake It Off' singer said: "I work out. I do spin classes, which are hard and I don't like doing them but I like how I feel afterwards. The reason I work out is because I work out is because I want to have endurance and I want to be able to hop on stage and sing a song and dance and not be winded."
When she isn't working or in the gym, Taylor, 24, loves indulging in some retail therapy or decorating her home.
When asked what she gets up to in her spare time, she said: "I enjoy shopping of course - I am female! And I've enjoyed furnishing my new place and working through the rooms to give each an individual feel. Whichever country I am in, I will try and see some of the city I am staying in and try and shop, though the busier I am, the more difficult this gets."
Taylor also shared how her retro-inspired album '1989' has changed the way she approaches getting ready.
She told Britain's HELLO! magazine: "I think there was a freedom to the clothes then and I see how that era had inspired modern fashion trends. So I'm wearing shorter skirts and things I would never have worn three years ago."

Rochelle Humes shops more for her daughter than herself.
The Saturdays singer loves exploring independent retail outlets but admits she is more likely to come home with garments for 18-month-old Alaia-Mai - her child with husband Marvin Humes - than to put in her own wardrobe.
She said: "I love little boutiques, they always have great cute things you've never seen before. I shop for [Alaia-Mai] more than I shop for myself."
The 25-year-old beauty is back in shape after having her daughter, but insists she took it easy after giving birth and allowed her body to naturally lose weight.
She said: "It's important not to stress out about it. You think that as soon as you've had the baby you need to go back to normal straight away, but my mum says it takes nine months to make a baby so it will take at least nine months to lose the weight. Take every day as it comes and make sure you feel comfortable, as your body does change."
Despite always looking glamorous, the 'Up' hitmaker insists she doesn't take too long getting ready.
She told Britain's OK! magazine: "I tend to wash my hair twice a week so my hair is always ready. Then make-up on top of that - I'd say about an hour."

Jessica Biel and Justin Timberlake are planning to move to his hometown of Memphis, Tennessee.
The couple are said to be expecting their first child together and are eager to raise their family away from the spotlight so want to leave Los Angeles.
A source said: "Justin and Jessica want their kids to have a hometown and a family base, and they definitely don't want to raise them in Los Angeles.
"Being near Justin's hometown is ideal because his mom, Lynn,
is even more excited about this baby than they are - and Justin's grandmother Sadie is on cloud nine.
"Justin's used to living in a small town and says he had a great childhood because of it."
Jessica, whose family live in the picturesque Boulder, Colorado, and was born in Minnesota, is more than happy to leave Hollywood behind.
The source told America's OK! magazine: "Jessica can't stand the obnoxious attitudes of kids in Hollywood. She wants her children to have good values and a sense of community."
The couple are said to have wanted a baby for some time, but wanted to wait until Justin had completed his '20/20 Experience World Tour'.
An insider previously said: "Contractually, he was obligated to do the tour, but he promised they could start a family when it ended."

Benji Madden gave Cameron Diaz a $25,000 black opal.
The 35-year-old rocker reportedly missed the 'Sex Tape' actress so much while he was touring Australia recently that he splashed out on the rare gemstone to show her how much she means to him.
A source said: "Cam thinks the opal is the most beautiful thing she's ever seen. She absolutely loves it."
The former Good Charlotte star decided to pick up the gift, which was sourced from an Australian mine, after being "amazed" at how the "deep-blue stone matched her eyes."
The couple got together in May after being introduced by Nicole Richie, who is married to Benji's twin brother Joel Madden.
Asked if she set them up, she previously said: "Yes. I'm going to take responsibility for everything!"
A source previously claimed they quietly got engaged recently and are planning to marry in the Napa Valley, California in the near future.
However, Cameron, 42, recently insisted: "I'm not looking for a husband or marriage or not not looking for that stuff. I'm living, not thinking what I should or shouldn't be doing with my life."

Myleene Klass was "heartbroken" to discover Benedict Cumberbatch was engaged.
The television personality was distraught when she found out the 'Sherlock' actor had proposed to his girlfriend Sophie Hunter, as she admits she's "in love" with his on-screen persona.
When Myleene - who divorced husband and father of her two daughters, Ava, seven, and Hero, three, Graham Quinn in 2013 - was asked who she would like to kiss under the mistletoe this Christmas, she shared: "I was a total Cumberbitch, so my heart broke the day I found out Benedict Cumberbatch is engaged. I actually think it's 'Sherlock' I'm in love with. I like them a bit odd, a bit quirky. The fact that he's a fictional character is a minor problem. Love will conquer all!"
However, the Littlewoods clothing designer revealed she already has her sights set on another famous actor.
As she shared her Christmas list, Myleene joked to OK! magazine: "[I want] Leonardo DiCaprio, a new bag and a really happy Christmas with my girls, watching them open their presents."

Mickey Rourke won his boxing match against Elliot Seymour.
The actor, 62, returned to the ring in Moscow, Russia, on Friday evening (28.11.14) to compete in an exhibition fight against a 29-year-old competitor, who he defeated in the second round.
Wearing a Stetson hat, a red and gold robe and shiny gold gloves, Mickey - who has been dating Russian model Anastassija Makarenko since 2011 - sent Elliot to the canvas twice before the fight was stopped and he was declared victorious.
The match was the star's first fight in more than 20 years, after deciding to focus on his acting career with films such as 'The Wrestler' and 'The Expendables', but said returning to the ring has helped him deal with his personal issues.
He explained: "I've got some things going on in my life so that [boxing has] sort of saved me from myself,
"And for a man like me, it's better to live in fear than go on in shame."
Having trained as an amateur boxer as a youngster, the star returned to the sport in the 1990s for three years, and boasts a career in which he went undefeated in eight fights. However, the star quit the sport following a number of facial injuries for which he required surgery.
After confirming his return to the sport on Friday, the Oscar winning actor - who shed 35lbs in preparation for the match - is expected to announce several more matches in the Russian capital in the coming months.
