Ellie Goulding and Calvin Harris were reportedly "holding hands" during a night out.
The 'Burn' hitmaker, who is dating McBusted bassist Dougie Poynter, has been good friends with the superstar DJ for a number of years but witnesses claim they appeared closer than usual at London's Mahiki nightclub on Saturday (21.06.14) after Capital FM's Summertime Ball at Wembley Stadium.
A source told The Sun newspaper: "Calvin and Ellie have been friends for a while but they appeared more than that this time around.
"They were seen holding hands and hugging at the club and more than a little bit all over one another."
Calvin, 30, and Ellie, 27, have been back in the recording studio recently after their song 'I Need Your Love' became a hit last year and they were filmed kissing in the video for the track.
Ellie uploaded a number of photographs of the pair working on new material on her Instagram account and fans were quick to point out how great they look together.
Meanwhile, Calvin has just split from 'I Will Never Let You Down' hitmaker Rita Ora, who was also seen with a mystery man on Saturday night at London's trendy new nightspot Chiltern Firehouse.
Calvin reportedly ended his year-long relationship with Rita, 23, by announcing their split on Twitter and the singer was left "embarrassed" by the shock announcement.

Louis Tomlinson is planning to charge fans £250 for a selfie with him.
The One Direction star recently completed his takeover of Doncaster Rovers soccer club and in a bid to raise funds for the team he's offering his fans the chance to have their picture taken with him in return for a £250 pledge.
The 22-year-old heartthrob - along with his business partner, former Doncaster Rovers chairman John Ryan - has launched a campaign on Crowdfunder and has set a £2 million target for the League One side.
The Tomlinson Ryan Trust have donated a six-figure sum to show their commitment and have so far raised £553,617 for the South Yorkshire club by offering soccer and One Direction fans a number of incentives, including photos with Louis and thank-you videos from the star.
Louis - who is a lifelong fan of his hometown soccer club - said: "I want to see the Doncaster Rovers supporters get the club the success it deserves ... This is a big step which I believe will open up opportunities to provide a very, very exciting future for the club and its supporters."
However, fans will be left disappointed if the £2 million sum is not raised as pledge rewards will only be given out if the Trust reach their target.

Kenny Ireland is reportedly battling cancer.
The 'Benidorm' actor, who plays the Solana hotel's resident swinger Donald, has sadly pulled out of the ITV sitcom's upcoming summer series after being diagnosed with the disease and is now focusing on his recovery.
A source told The Sun newspaper: "The diagnosis was crushing for Kenny and his family. This is obviously a very difficult time for them and they are coping as best they can.
"The priority is Kenny's health. As soon as he was given the news he pulled out of the latest series of 'Benidorm' which, of course, everyone understood."
A spokesperson for Kenny declined to comment, but confirmed he wouldn't appear in new episodes of the popular show, which is about to embark on its seventh series.
The Garvey family have also checked out of the programme, with Mick (Steve Pemberton) Janice (Siobhan Finneran), Madge (Sheila Reid), and Michael (Oliver Stokes) receiving a big send off in the new season's opening episodes.
Steve recently explained: "We've left 'Benidorm'. We filmed our scenes early on this year so we're going to be in the first episode or two of the new series, but then the whole Garvey family are leaving."

Example gets abuse about his voice on Twitter.
The 'Kickstarts' hitmaker's upcoming fifth album 'Live Life Living' has cemented his transition from rapping to singing, and despite receiving criticism about his vocal prowess on the social network, the musician feels confident about his ability to convey emotion in his voice.
He told Digital Spy: "I think there's some people who don't like my voice and that's fine and the reason they don't like it is probably because of the sound of it.
"I often get tweets going, 'You can't sing, you're f**king awful' but then I get hundreds of tweets a day saying, 'I love Example's voice - it's so unique and gravelly and has so much emotion in it'. I don't think there's been anyone in history where everybody loves their voice."
Example denied having a course of singing lessons and feels like his music actually benefits from his lack of vocal training.
He explained: "I had one singing lesson and it was mainly to learn how to warm up my voice. I said shall I come back for more lessons and she said, 'Well you've got such a unique sound to your voice I don't think I can teach you to sing'.
"I think if you start to learn to sing in the traditional sense you lose all the character in your voice."
The star is relieved marrying model Erin McNaught helped him give up his party lifestyle because he was becoming a "self-destructive" person.
He reflected: "I mean there were some amazing, fun moments, you know? Like just being able to do whatever you wanted when you wanted, but it was very self-destructive and I didn't really like me as a person.
"I didn't really like who I was and a lot of my friends didn't like me, my ex-girlfriend didn't like me and my family didn't really like me back then in like 2010. I'm in a much better place now."

Ryan Thomas doesn't want any more children.
The 'Coronation Street' star - who has daughter Scarlett, five, with former co-star Tina O'Brien - admits becoming a dad at a young age was tough and he isn't sure he could have another child to look after.
He said: "It's such a big responsibility to be a parent. You have to sort of give up your life for them in a way. Having one's hard but having more ... it's just a lot of responsibility and I'm not sure if I want that again.
"I was just so young. I've always been there for Scarlett, but I'm just not sure I want to go through all that again, although it's getting easier now Scarlett's getting older.
"Then again, if you meet someone you love, you might end up having more children, so who knows."
The 30-year-old hunk is in a relationship with Bollywood actress Amy Jackson, 23, and says he can't wait to go out to India to see her in her element.
Ryan told Britain's OK! magazine: "She's going again in July then her film is out in August, so I'd like to go over with her for that. I know in certain areas she's crazy famous and it would be nice to experience what it's like for her."

Millie Mackintosh says she has a "whole new group of friends" after quitting 'Made in Chelsea'.
The 24-year-old beauty, who left the E4 show last year prior to her wedding to Professor Green, has revealed she doesn't keep in touch with many of her former co-stars, except Rosie Fortescue, and has moved on from the show and made new pals.
She explained: "I'm really missing Rosie while she's been in New York [filming 'Made in Chelsea: New York']. I'm jealous that we didn't get to film out there but I did some amazing trips like Morocco and Cannes.
"I saw Caggie [Dunlop] recently but I've made loads of new friends. You have friends in your teens and then you make a whole new group of friends in your twenties.
"I don't speak to many people in 'Chelsea'. I stay out of it. I don't even watch it!"
Fashion fan Millie is currently competing on the latest series of BBC cooking competition, 'Celebrity MasterChef', and can't believe she's working alongside supermodel Jodie Kidd.
She told Britain's OK! magazine: "I've met some of the other people who'll be on it. Jodie Kidd is a lot of fun and a great cook, and Lesley Ash is lovely. The girls stick together, but there are some dark horses."

Kelsey Grammer wants to reprise his role as Beast in a future 'X-Men' film.
The 59-year-old actor made a brief cameo as the ape-like mutant superhero at the end of the Marvel franchise's most recent instalment, 'X-Men: Days of Future Past', and would jump at the chance to play the part again.
He admitted to Collider.com: "I hope to do another. I hope they find some way to come up with a new story that involves Beast in my timeline."
Grammer, who first appeared as Beast in 'X-Men: The Last Stand', revealed he took the initiative to call director Bryan Singer and asked to make a return because he had such fun filming the 2006 movie.
He said: "Actually I called Bryan. I bumped into Hugh Jackman and he said, 'Oh you're gonna be in another X-Men, mate!' and I said, 'No I'm not, I don't know anything about it.'
"So I made a couple of inquiries, got a hold of the script, found out that it's primarily dealing with the past and that timeline I don't have a place in, but I saw that at the end there was this coda where he made an appearance. I said, 'Listen, I really want to be involved,' so Bryan arranged for it and I had a lovely time."

Lindsay Lohan reportedly ran around Selfridges in the nude.
The 'Mean Girls' actress shocked onlookers at the plush London department store when she allegedly charged out of her dressing room and started racing around the shop in the buff, laughing hysterically all the while.
A source told The Sun newspaper: "Lindsay took some items into the changing room. Halfway through, she ran out of the room with nothing on and was chased by members of staff who were trying to cover her up.
"She was laughing her head off and literally giving staff the run-around as customers looked on."
Lindsay, 27, was due to meet with a personal shopper at Selfridges later that day, but subsequently cancelled her appointment following her bizarre display.
The insider added: "Lindsay was booked in for a personal shopping experience with a posh brand at the shop later that day, but it didn't happen."
The flame-haired beauty is considering a permanent move to London and is being lined up for a role in West End show 'Speed-the-Plow', which will reportedly open in November.
Lindsay, who completed a court-ordered stint in rehab last year, has started house-hunting in the city and feels she has found her spiritual home after enjoying a series of judgement-free nights out in the UK.
A source previously said: "Lindsay's convinced everyone in America is out to get her, but she's had the opposite experience in London.
"She loves British culture and says people have treated her with respect for the first time in years. Now she's looking into the immigration process and planning a full-time relocation."

Kenan Thompson has become a father for the first time.
The 'Kenan and Kel' star's wife Christina Evangeline gave birth to a daughter called Georgia Marie on Friday (20.06.14) and the couple are said to be ecstatic.
The baby weighed in at six pounds when she arrived at 10:30 a.m. at a New York City hospital, TMZ is reporting, and the 36-year-old 'Saturday Night Live' comedian hasn't slept "a wink" since.
Kenan first revealed he was going to become a father during an appearance on 'Late Night With Seth Meyers' in March.
He enthused: "I'm about to be a daddy! That's right! Papa Kenan."
The Nickelodeon star joked that he planned to be "at the casino" when his wife of two years gave birth because he was so nervous about their new arrival.
He said: "I am terrified. I don't know what to do with babies. Like, do you feed it and like, put it away or something?"
Christina shared two pictures of the happy family on Instagram over the weekend, captioning an image of her cradling baby Georgia to her chest, "We're just really sleepy."

Gwyneth Paltrow and Chris Martin haven't ruled out a reconciliation.
The former couple, who announced their split in late March after 10 years of marriage, have reportedly become a lot closer again after enjoying lots of intimate outings with family and friends.
A source said: "They haven't made any concrete decision to get back together, but it's a possibility. They're discovering a dynamic that works for them all over again, like when they first got together. They're getting along really well."
The 41-year-old actress and the Coldplay frontman, 37, are still living together in California, as they wanted to make their separation as easy as possible for their children, Apple, 10, and Moses, eight.
However, the insider told People magazine: "They've loving time together with and without the kids. She didn't want to end the marriage. He's been a great father, and that has helped keep the flame alive. They love each other, and if the romance comes back, they'll go with it if it feels right."
The pair sparked speculation recently that they were giving their relationship another go after they were spotted giggling over a romantic meal in California earlier this month.

Chris Hemsworth has banned his wife from posing for Playboy.
Elsa Pataky, who has daughter, India, two, and three-month-old twins, Sasha and Tristan, with the 'Thor' star, is reportedly desperate to show off her incredible post-baby body in the magazine, but the hunky actor believes it "inappropriate" for her to flash the flesh.
A source told America's Star magazine: "She said it would be a great career move, but Chris wanted nothing to do with the conversation. He said it would be inappropriate for a woman with such young children to pose naked."
The Spanish actress has sprung back into shape following the birth of her twins, but admitted two months ago that she wasn't rushing to get back in the gym after her specialist had advised her against it.
She said previously: "In my case a specialised post partum physiotherapist recommended not to work my abs until they were totally joined again.
"As you know, when you're pregnant the abdominals separate as the belly grows. So you have to wait for your abs to return to its initial position before you start doing ab work or otherwise there may be a lump, like a belly that never goes away."
Instead, Elsa had been making up healthy juice concoctions to help kick start her weight loss.
She said: "The juice I like to drink once in a while and that helps me to clean my system is made with a blender: an apple, a carrot, some celery with the green leaves, a lemon without peel. Once it's done, you add a few teaspoons of olive oil. Super good."

Lana Del Rey is inspired by Courtney Love.
The 'Summertime Sadness' hitmaker has always looked up to the Hole frontwoman and rock 'n' roll legend, so feels proud to count her among her friends these days.
She said: "Courtney Love's a big inspiration. I like her, I talk to her a lot. I just went her show ... when she was playing in London. I like people who are similar to her, like Joni Mitchell types or Stevie Nicks, who are both strong female characters."
The 27-year-old star was strongly influenced by jazz legends Nina Simone and Billie Holliday on her second album 'Ultraviolence', and hopes she has done their musical legacy justice.
Speaking on France Inter radio station's 'Laura Leishman Project' show, she said: "It has a Pacific coast feel to me, I think it's guitar driven, there are references to Nina Simone. That's why I ended the track listing with a cover of 'The Other Woman'. I am inspired by early jazz culture. It's a West coast jazz fusion with a little bit of East coast fever."
