Jennifer Aniston loves singing and could have a successful music career, according to boyfriend John Mayer.
The Friends star is shy when it comes to showing off her voice, and only does it when she thinks no one else is listening.
But Mayer is so impressed by the actress' vocal talents, he's convinced she could become a recording artist.
He tells America's OK! magazine, "Do you know that girl can sing...? She does it when she doesn't think anybody's paying attention.
"I said to her the other night, 'There's a track in there.' I think she could... kill it."
