Keegan Michael Key cast in 'Gary'

Actor joins comedy as a regular

Keegan Michael Key is joining the cast of CBS' comedy series "Gary Unmarried" as a regular.

"Gary," which returns in the fall for its second season, stars Jay Mohr as Gary, a newly divorced painting contractor juggling custody of his two children, a controlling ex-wife and his hot new girlfriend.

Key will play Clean, Gary's old high school friend, a former minor-league baseball player who had a promising career until sidelined by a knee injury. Gary and Clean reconnect and pick up their friendship where it left off, alternating between best buddies and competitors.

Season 2 of "Gary" premieres Sept. 23.

Key, who next appears in Sony's feature "Born to Be a Star," is repped by UTA and Principato-Young.
