'The Challenge: Battle Of The Exes': The Final Three Must Jump Into A Frozen River (VIDEO)

The final three teams left on "The Challenge: Battle Of The Exes" (Wed., 10 p.m. ET on MTV) got to visit Iceland in all its snowy winter beauty.

However, they also had to strip off to their undies and jump into a freezing river to complete a challenge and earn their next artifact.

CT and Diem posted the fastest time, which meant they got the most comfortable sleeping arrangements on the glacier. Johnny and Camila were in second place, with a disappointed-looking Ty and Emily trailing in third.

"The Challenge: Battle Of The Exes" continues on Wednesdays at 10 p.m. ET on MTV.
