Actress-turned-singer Minnie Driver has hit out at critics who undermined her move into the music industry, slamming their derisive speculation as "absurd" and "vicious".

The GOOD WILL HUNTING star recorded her debut album, EVERYTHING I'VE GOT IN MY POCKET, in 2004, and immediately faced a barrage of scepticism that she was merely cashing in on her Hollywood fame.

She says, "People threw their hands up and said, 'Why is she doing this? Why does she think she is capable of becoming a singer?'

"It was an absurd, as well as a vicious, argument. Anyone who has that weird volition to become an actor probably has a weird volition to do lots of other creative things.

"The next thing everyone asked was, 'Who was each song on the album based on?' Like, 'Was that one about (former boyfriend) Matt Damon?' As if I'd say anyway."
