'The Challenge' Season 34 Cast Is Full Of Alums From 'Love Island,' 'Big Brother' & More

MTV

For the first time since The Ruins back in 2009, The Challenge will feature a two-team format. Its upcoming 34th season splits The Challenge: War of the Worlds 2 cast into two groups: 14 Brits and 14 Americans. Together, they'll compete for the chance to share a $1 million prize. Among those duking it out are reality TV legends and rookie competitors alike, but while the latter may be fresh to the show, they're no strangers to reality television: alums from Big Brother, Love Island, and Ex on the Beach UK are all included in the cast.

There's also a twist. In addition to the two different teams, there are four designated "reinforcements" who are not initially assigned to Team U.S. or Team UK. These cast members are CT Tamburello, Turabi "Turbo" Camkiran, Dee Nguyen, and "Ninja" Natalie Duran. The winner of the first challenge will get to pick two reinforcements to stay on their team for the remainder of the season.

Of course, let's not forget the one cast member who fans expect to see every season: TJ Lavin is back to host The Challenge and inevitably lecture anyone who merely thinks about quitting a challenge. Everyone knows how much TJ hates quitters. Hopefully, there aren't any in this cast. Here's where you've seen everyone before.
