ENEMIES ARE REUNITED WHEN MTV'S "THE CHALLENGE: RIVALS II" PREMIERES WEDNESDAY, JULY 10 AT 10:00 P.M. ET/PT

New Season Trailer Set to Debut Tonight During All New Episode of "Teen Wolf"

One-Hour Launch Special Hosted by Nicole "Snooki" Polizzi and Kenny Santucci Airs Wednesday, June 26 at 10:00 P.M. ET/PT

Santa Monica, CA (June 10, 2013) - MTV travels to Thailand when 16 men and 16 women return to one of the Challenge's most exciting recent formats. "The Challenge: Rivals II" premieres on MTV Wednesday, July 10 at 10:00 P.M. ET/PT. Playing in teams of two, Challenge cast favorites are forced to pair with only one person: their bitter rival. And with more money than ever before at stake, the competition turns explosive.

"The Challenge: Rivals II," hosted by TJ Lavin, pits enemy alongside enemy and asks the question: What do you care about more - old grudges or big money? Some pairs like bad boy CT and master manipulator Wes have been going at each other for years, while others like Frank and Johnny have beef because of a Twitter war! All kinds of rivalries are here, from Challenge veteran Paula, who hooked up with her partner Emily's ex, to Diem and Aneesa, former friends who betrayed each other on a past Challenge. But if you think the drama is in the past for these competitors, think again. The surprises start immediately when a twist sends shockwaves throughout the house, not to mention when a new girl hooks up with CT right under his ex Diem's nose. And that's only the beginning for these Rivals.

A sneak peek of the new season will premiere tonight between 10:00 - 11:00 P.M. ET/PT during MTV's "Teen Wolf." For an advance look, check out the trailer here.

On Wednesday, June 26 at 10:00 P.M.
