Happy Endings Pictures of Brian Austin Green

Season two of Happy Endings has been so much fun that we're sad that the season finale is tonight. However, we were thrilled to hear about who's making a guest appearance from star Eliza Coupe: original Beverly Hills, 90210 cast member Brian Austin Green (who didn't love David Silver?)! He'll be attending Derrick's wedding along with the rest of the Happy Endings crew. Even though there appears to be a strict tuxedo policy for all, it looks like he'll be warming up to our girl Penny. Click through to get a taste of what you have to look forward to.
