Posing on the cover of Revolver magazine's "Hottest Chicks in Hard Rock" issue in black thigh-highs and towering heels, it looks like Taylor Momsen is doing everything in her power to prove she's all grown up and tear down whatever's left of the good girl who starred as Cindy Lou Who in 'How The Grinch Stole Christmas.'

The photo spread shows Momsen, lead singer of The Pretty Reckless, in various states of undress and clutching a variety of weaponry, including chainsaws, shotguns and swords. But it's what the 17-year-old starlet is saying that's likely to cause a bigger stir.

"If it's a good sex tape, I'll watch it ... I like some adult stars. I have a couple favorites. But I will say this: That Tommy Lee-Pamela Anderson video wasn't very good. I wouldn't f**k Tommy Lee," the singer says.
