Chelsie is killin' it! Can she make it three in a row and be the first babe in history to make it into the Model Melee Hall of Fame?

Returning (again!) as a 2x champion, Chelsiearyn (left) is Playboy’s 2011 Miss Social March, a motorcycle enthusiast, bad boy lover and MMA and NY Jet fan. Her new opponent this week is MsKelElizabeth from Detroit -- a poker centerfold, clothing model, sports and music addict, and animal advocate.

Which pic is hotter? Vote as often as once an hour, and the winner will advance to the next round! Voting ends on 4/18 at noon, EST.

Official Rules

The winning girl moves on to challenge another girl next week. If one woman dominates and wins four weeks in a row, she makes the ‘Model Melee Hall of Fame’ and gets retired from the competition. At the end of the year, all Hall of Famers will return, to face off in the crowning of the ‘Grand Hot Twitpic Champion’ (or something – we will come up with a better title by then.)
