Will Gwyneth Paltrow be believable as a country singer in her upcoming film, Country Strong? Well, she already has her kids convinced. According to the actress Apple, 6, and Moses, 4, think their mom is a famous singer after she spent the last year learning to play the guitar and honing her singing skills for her latest role.

"My kids have never seen me in anything. I mean, they know I work but they think I do singing, which is hilarious," she says.

"They probably saw me for a year practicing my guitar and singing and they think that's my job."Gwyneth, who is married to Coldplay frontman Chris Martin, recently had a guest role on Glee. But the actress admits she had never heard of the show until she was offered the part of substitute teacher Holly Holiday.

"I was like, 'What is 'Glee'?," she laughed. "I live in a cave, and my brother was like, 'You have to do it. It's this amazing show.'"So then I started watching it and I got totally obsessed with it, to the point where I got on set and I was kind of star-struck."
