Penn and Blake started dating during Gossip Girl's first season, but they broke up amicably in 2010. "I'm so happy for her," he says, adding that Blake and Ryan's relationship is "everything that it should be."
Blake and Penn are still friends, but it looks like Ryan and his new wifey didn't want any exes at the wedding. In fact, Penn heard about Blake's big day by reading the news and chatting with "people who are close to her."
Sigh, Lonely Boy. At least you have your muppet hair!
