Washington, Dec 16 : Besides acting, Hollywood actress Jennifer Aniston is a talented singer, according to beau John Mayer.

Although the `Bruce Almighty' actress is shy when it comes to showing off her singing talent, Mayer thinks she is good at crooning.

"Do you know that girl can sing...? She does it when she doesn''t think anybody''s paying attention," Contactmusic quoted Mayer, as telling OK! Magazine.

"I said to her the other night, ''There''s a track in there.'' I think she could... kill it," Mayer added. (ANI)
