Jennifer Aniston has the potential to ditch acting in favour of a pop career, according to boyfriend John Mayer.

The actress - who is busy promoting her upcoming film Marley & Me - has apparently been flexing her vocal chords in secret.

And according to John she's not bad either: "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."

Meanwhile Jen seems to be focused on change right now, having expressed a desire to step away from acting for a while.

She told the Mirror, “There are other things I want to explore besides acting - maybe something outside my comfort zone, something to do with other people or something with children."

So she wants to be Angelina Jolie, then.
