Many great movie stars have a trademark that fans expect to see in their films. Gwyneth Paltrow's hook? Sex.
"There's always some sex and nudity when I'm involved," Gwyneth admitted when ET's Mark Steines asked the mother of two how she felt about doing romantic scenes now that she has a family.
In her new movie 'Country Strong,' Gwyneth plays Kelly Canter, a fallen country-music star who has succumbed to alcohol addiction. While in rehab, Kelly begins an affair with one of the employees, Beau Hutton (Garrett Hedlund), who struggles to keep his life in balance when he finds abrupt success as a singer/songwriter. Following her stint in rehab, Kelly's husband James (Tim McGraw) books her on a comeback tour featuring up-and-coming singers Chiles Stanton (Leighton Meester) and Beau, forming a dangerous love triangle.
Gwyneth married Coldplay frontman Chris Martin in December 2003 and she says that now she has even more respect for his profession.
"When I signed on to do it I didn't realize how much I was biting off in a way," said the Oscar winner. "But to learn how to play guitar, just even enough to just be pressing the right chords, was a lot of work and the singing was a lot of work and the research and learning about country music and listening to everybody and watching DVDs of everybody performing and, you know, it was a lot of research."
Leighton also had some scantily clad moments in the movie and she compared shooting a scene in her underwear to being filmed in a bathing suit, saying that "in the right environment" salacious scenes are painless, unlike the audition process for the movie which the actress called "intense."
The "Gossip Girl" star told Mark how she found out that she'd booked the part: "I was at a diner in New York," said Leighton. "And then they called me and I missed the call. And then I sat there and I was eating French fries and I was like, 'What? What is it?' They were like, 'It's happening.' And so I cried a little bit and I was really excited and all my friends were really happy for me."
Garrett couldn't play the guitar or sing before he took on his role, but he told Mark that he enjoyed the challenge, saying, "You fail and then you get a little better and then somebody tells you that. And then you got that amount of confidence to kind of ride you to and to the next step and to keep raising the bar."
Whereas Gwyneth, Leighton and Garrett couldn't wait to jump on board the project, the film's real-life country star, Tim McGraw, hesitated when offered the role, because he thought his presence in the movie might be a distraction.
"Because the last thing you want is an audience to come in and just start, every time I'm on the screen, say, 'Isn't that that country guy that sings?'" said Tim. "You don't want that to happen."
'Country Strong' strolls into theaters January 7. Watch the clip to see what Gwyneth said about her recent "Glee" appearance.
