The One Day star often finds the pressures of fame - especially the media attention - hard to deal with so has penned a track which helps relieve some of her frustrations.
Anne - who is currently shooting Batman movie The Dark Knight Rises, inwhich she plays Catwoman - told talk show host Conan O'Brien: "With all the stuff that's been going on with Batman, the paparazzi attention's been a little intense so I actually wrote a rap song about it. It's in the style of Lil' Wayne."
She then went on to reveal the tune, rapping: "Yo I'm a paparazzi/ I don't play no yatzi/I go pap-pap-pap my camera's up your crutch/ See I tell the truth from what I see and sell it to Perez Hilty/ Don't call my scuzzy making money that's my job celeb photography/ What hell no I'm not needy I'm legit no stalk-a-razzi don't act so hartzy tartzy bitch I know that you're from Jersey/ Pap-pap-pap-pap scream all you want won't make me stop/ Pap-pap-pap-pap I know you love to feel my pop."
It seems Anne has been in contemplative mood about her life recently, as she also revealed she thinks life is "f***ed up".
The 28-year-old star - who was shocked in 2008 when her then-boyfriend Raffaello Follieri was jailed for four-and-a-half years for fraud and money laundering - said: "People deal with horrible things all the time. Somewhere, someone is battling cancer. Someone has lost their job.
"Life is really f***ed up and it's really painful sometimes.
"I think it's unusual for someone in a position of prominence to go through something like that, but it's not really unusual in life."
