They're back! Starting Wednesday, July 10, 32 cast members from past Real World and Challenge seasons will be battling it out for $350,000 on MTV's The Challenge: Rivals 2.

The show's premise is sure to create drama -- 16 women and 16 men will be divided into two-person teams, with one of their most bitter rivals serving as their partner. The rivals will have to work together to win -- all while competing in strenuous activities in the show's atypical fashion. The season was filmed in Thailand, where 2009's Challenge: The Ruins was shot.

Surprisingly, exes Diem Brown and CT Tamburello will both be back, competing on separate teams this time around. The couple became a fan favorite during 2007's The Duel after Tamburello helped Brown recover from ovarian cancer, but split two years later. Despite the time apart, the former flames endured many tension-filled moments on The 2009's Duel II and then on 2012's Battle of the Exes.

Brown is currently in remission after a second bout of cancer, but hints to Us Weekly that competing alongside her temperamental ex was not easy. "Things are more complicated than ever!" she says. 

2011 Challenge: Rivals winner Paula Meronek is also competing again, as well as Johnny "Bananas" Devenanzio, who's a four-time Challenge winner, having won in 2008, 2009, 2011 and 2012. Devenanzio holds the title of having won the most challenge prize money ever -- totaling $266,543 thus far.
