'Happy Endings': Brian Austin Green to guest star in the season finale

Brian-Austin-Green.jpgIn some of the best casting news ever, Brian Austin Green will be guest-starring in the season finale of "Happy Endings," according to EW. The star of "90210" and "Terminator: The Sarah Conner Chronicles" will be joining one of the funniest casts on television. We're hoping this won't be the last time!

In the episode, Green will be part of a wedding. He'll play a charming man who appears at the wedding of Penny's ( Casey Wilson) second gay best friend Derrick ( Stephen Guarino). He'll be doing some hard core flirting with Penny, but he's not in the best physical state. Um, we've seen those muscles. Can't imagine how they're going to manage that!

The episode airs April 4th and will bring the return of Brad's ( Damon Wayans Jr.) boss ( Larry Wilmore). We're not sure how anything can top Penny's "whore's bath" monologue from last week, but we can't wait to see it!
