'Gossip Girl' star Taylor Momsen has often portrayed herself as the bad girl of entertainment, and an incident that involved her dog's testicles reveals how far she would go.

Momsen, 17, who fronts the rock band, The Pretty Reckless, has been revealed by her band mate, guitarist Ben Phillips, to have an affection for pyromania and a desire to be a badass.

"Taylor loves setting things on fire ... she thinks we're some rock 'n' roll badasses," the Daily Telegraph quoted Phillips as saying.

"One morning, Taylor got into the studio really early - she'd just had her dog neutered and brought in the bits. Which she then burned.

"We were grossed out," he stated. (ANI)
