If you were hoping for complete insanity this season, welcome to Episode 3. The Bad Girls had to use their brains in a challenge — or get pelted with brains, literally.

The alliance between Camilla and Elease is shattered, Rocky messes up her leg, and one Bad Girl goes home — despite what she heard from her scheming teammates.

“Bad Girls: All-Star Battle” Season 2 pits 16 of the most memorable girls in “Bad Girls” history under one roof to compete in a series of over-the-top physical and brain-teasing challenges for a chance to win $100,000 and the title of “Baddest Bad Girl of All Time.”

Returning with musician, actor and heartthrob Ray J (@RayJ) as host, the competition ups the ante for the sophomore season with more girls and outrageous challenges including a twerking match, a stiletto standoff, mud wrestling, and a daring eating contest with fish eyes and cockroaches.

“Oxygen amped up the challenges to a whole new level,” says Host Ray J. “Emotions ran high and the Bad Girls went hard. It was a much bigger game, but they always kept their eyes on the prize. If you thought it was crazy in season one, wait until you see this season.”
