Country singer Jo Dee Messina has joined the cast of CBS' "Secret Talents of the Stars," the weekly celebrity talent show that will reveal the unknown talents of 16 well-known personalities.

Messina will train with choreographer Dave Scott ("Step Up") to perform an urban dance, blending hip hop and step, with a supporting troupe.

As previously reported, country star Clint Black will be performing stand-up comedy, Mya will demonstrate her tap-dancing prowess and Sheila E. will juggle with the Flying Karamazov Brothers on the show.

The show, which will employ a fan-voted playoff format, will premier on April 8 at 10 p.m. ET.
