The Joey & Melissa star and ESPN2's SportsNation presenter will front the celebrity competition when it premieres on March 19.
The show - based on the Dutch format Celebrity Splash - sees ten contestants train and compete in regulation platform and springboard diving.
Kendra Wilkinson, Katherine Webb and Drake Bell are among the stars taking part in the programme, along with Louie Anderson, Chuy Bravo, Nicole Eggert, Keshia Knight Pulliam and Ndamukong Suh.
Rory Bushfield and Kareem Abdul-Jabbar complete the lineup.
They will be mentored by diving icon Greg Louganis, and judged by US gold medallist David Boudia and USA Dive Team director Steve Foley.
Model Webb recently described the idea of competing on Splash as "fun" and "crazy".
Discussing her training sessions, she revealed: "I think I face planted the other day. I was trying to flip off the dive and I ended up face planting and I come out of the water and I'm stinging all over.
"But hopefully nothing like that will ever happen again, so we'll see."
