Taylor Momsen wrote for Heidi Montag

Taylor Momsen has revealed that she was responsible for Heidi Montag's single Blackout!

The actress and singer revealed that she wrote the song at only 9 years old.

Taylor told Sugar magazine, "When I was 9 I wrote a song called 'Blackout'. And I think that Heidi Montag just sang a song that a 9-year-old wrote. So that's what I think about that."

But although she wrote for one of the *cough* top pop talents of her country *cough*, Taylor still has no desire to go into that area. Because she's rock remember. Rock.

She said, "That was never a choice for me. It wasn't 'should I go pop or should I go rock?' I'm a rock chick living in a pop world.
