Penn Badgley might have played Dan "Lonely Boy" Humphrey on Gossip Girl, but in real life he couldn't be more loved. The 30-year-old actor and MOTHXR frontman tied the knot with girlfriend Domino Kirke - again - on Saturday. The duo originally got married in February at a courthouse in Brooklyn surrounded by friends and family (including Domino's sisters, Girls star Jemima Kirke and Mozart in the Jungle actress Lola Kirke), but decided to throw another reception with celebrity guests like Mariska Hargitay, Zac Posen and Debra Messing over the weekend. See every detail from both of their weddings ahead.
