Sarah Harding says kissing Dominic Cooper was "weird".
The Girls Aloud beauty - who is dating DJ Tom Crane - found it strange locking lips with the 'Mamma Mia!' heartthrob for her acting debut in UK TV show 'Freefall'.
She said: "It was very weird, not in a bad way, mind. It's just that when you're kissing someone other than your boyfriend, you just feel a bit wrong.
"But it didn't feel like a real kiss. The room was full of people getting us to do it again. I just ended up laughing during the takes. It was very awkward.

"Dominic is a very good-looking, though, and as it was my first on-screen snog, I could have done a lot worse."
Sarah admits she's nervous about Tom watching the kiss as she knows he's uncomfortable about her locking lips with another man.
The blonde beauty added: "He hasn't seen it and I'm scared! I don't think he could watch me doing that, he's a man's man. He doesn't like the idea, even though he knows it's only acting, but he's proud of what I've done. He's met Dominic and they get on really well."
Sarah Harding has ditched partying for gardening.
The wild Girls Aloud singer, who has moved to the English countryside with her DJ boyfriend Tom Crane, claims she would rather stay at home than attend showbiz events.
She said: "I'm a real homebody now. I love to potter around and chill in the garden. I'm becoming quite house-proud - it's really sad. I don't think I was ever completely wild, though."

Sarah, who recently enjoyed a raucous holiday with friends on the Spanish party island of Ibiza, also insists she is "boring" until she has a drink or performs live with her bandmates.
The 27-year-old blonde beauty explained to Britain's Heat magazine: "My lairy side comes out when I'm on stage or out for the night, but behind closed doors, I'm much more chilled out. I watch films and play with the animals. I'm actually quite boring."
Sarah Harding has reportedly got engaged.
The Girls Aloud beauty - famed for her wild partying - was overjoyed when DJ boyfriend Tom Crane proposed to her last weekend and the pair are already said to be planning a lavish wedding, including DJ sets and performances from their musical friends.
A source close to Sarah - who showed off her ring at a Music Industry Trust dinner on Monday (03.11.08) - revealed to Britain's Daily Star newspaper: "Sarah is very rock'n'roll. And Tom is obviously passionate about his music as well, so they are planning the mother of all rock 'n' roll weddings."
Tom, 28, has revealed he and his 26-year-old fiancee are already making plans to have children once they have tied the knot.

Meanwhile, Sarah has spoken out about a terrifying head-on collision she had with a double-decker bus, saying she was unhurt but deeply embarrassed.
She explained to Britain's Daily Mirror newspaper: "I was moving house, we had the builders in and my mum was down to visit.
"I jumped in the Range Rover and because I'm just getting used to the roads around my house, drove up a one-way street."Unfortunately there was a bus hurtling down the other way and it rammed my car into these bollards on the other side of the road."My tyres burst, the alloys are trashed and everyone on the bus had to get off because it had totally blocked the road."It was awful - plus I was so embarrassed. Then after that, I got the hire car out and someone bumped straight into me."
The blonde singer has sparked further rumours the group are to disband after confirming she is collaborating with nu-ravers Filthy Dukes for the soundtrack of forthcoming film 'Wild Child'.
A friend of the star told Britain's Daily Mirror newspaper: "She was thrilled to be approached and recognised as a singer in her own right. The 'Wild Child' soundtrack is a pretty cool album with some big names on it including Rihanna, Robbie Williams and Nelly Furtado, so it promises to be a springboard to other things."
Sarah, 26, is the latest member of the band to branch out on her own, although her pal insists she is still committed to Girls Aloud.
The friend added: "She loves Girls Aloud and has no desire to for the band to split - but that doesn't mean she's not willing to expand her work."
Cheryl Cole recently provided backing vocals on will.i.am's track 'Heartbreaker', while Nadine Coyle has been dogged by rumours she wants to pursue a solo career.
'Wild Child' stars Julia Roberts' niece Emma and British actress Natasha Richardson.
