Apparently, Lily Allen got into a fight outside the Groucho club in London over the weekend, but while her punches were weak, she used the deadliest weapon in her arsenal to win. She used her nipple. Okay, not really, but while she was "fighting," the paparazzi caught yet another Lily Allen nipple slip. If Lily Allen was a superhero, her Kryptonite would be not showing her nipples.
Lots more pictures of Lily Allen, the Fearsome Fighter, after the jump.
