Paltrow has lost appetite over singing debut

Gwyneth Paltrow is something of a nervous wreck as she preps to make her live country music singing debut at Wednesday's Country Music Awards (CMAs) in Nashville.

Paltrow, 38, will croon "Country Strong," the title track from the upcoming flick of the same name in which she plays a down-at-the-heels singer striving for a post-rehab comeback.

"I actually feel better this week about singing the song on the awards show," the actress told Reuters Monday at the movie's Nashville premiere.

"I was really bad last week; I lost my appetite and I couldn't sleep," the married mother of two added.

Closer to the big night, she says "I feel prepared this week. If I can keep my nerves under control I can survive it."
