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`, in which 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."
