Another cast member has been announced to appear on Season 5 of "Glee." According to Deadline, a new "mean girl" will be joining the cast as a member of the Cheerios.

Actress Erinn Westbrook will have a recurring role on the new season as a sassy cheerleader who shakes things up at McKinley High. It hasn't been revealed when Westbrook's character, named Bree, will make an appearance but it has been revealed that at the beginning of the season the cheerleading squad will be coached by Roz Washington (NeNe Leaks).

Westbrook joins several other new names on season five. Back in August Chris Colfer revealed on "Live! With Kelly and Michael" that Adam Lambert would also be playing a mean kid.

"Oh yeah! Apparently Adam Lambert is joining the show and he's going to play my nemesis" Colfer said, who plays Kurt on the show. "I always wanted to see Kurt be mean. I know no one else does, but it'll be fun for me."

Demi Lovato will also be joining the cast as Dani, a struggling artist who becomes Santana's (Naya Rivera) love interest. The "Heart Attack" singer recently told Ryan Seacrest on his radio show that she was honored to play a lesbian on the show.

"I don't want people to take from this, 'Oh my God, Demi is kissing a girl.' I want people to take from it [that] this is actually an incredible step in our generation today where I'm able to play a young lesbian on primetime TV," she said. "I'm honored to be able to... hopefully inspire people with my character to be who they are and not be afraid of it or ashamed."

The new season of "Glee" premieres Sept. 26 at 9 p.m. on Fox.
