Denise Richards is headed back to primetime!

The actress, 39, is joining the cast of Spike TV's raunchy football comedy Blue Mountain State in a recurring role as Debra, Ed Marinaro's hot-headed former flame.

"She plays the coach's ex-wife, and I think I sleep with her!" co-star Darin Brooks tells of Richards' role. "She's trying to get back at him."

Brooks' character is no stranger to wild hookups -- while playing the second-string quarterback last season, he had a liaison with former Dancing With the Stars wildcat Cloris Leachman!

The actor -- who has yet to film with Richards -- says she's been getting along famously with the rest of the Blue Mountain State cast.

"Everyone said she was really cool, really nice, it was great to work with her," he tells Us. "I'm really looking forward to sleeping with her!"

Blue Mountain State's second season premieres Oct. 20; Richards first appears in the third episode.
