Gossip Girl star Penn Badgley attended the GQ magazine 40th anniversary celebration of the first moon landing on Wednesday night, rocking his off-season beard.

Penn, who made his feelings on a future career in music known this week, is also giving hirsute co-star Ed Westwick a run for his money with the chest hair:

Penn looks a bit different than clean-cut character Dan!

Later that night, Penn joined his girlfriend (and fellow Gossip Girl cast member) Blake Lively for dinner at Five Points restaurant. The couple was joined by Blake’s Sisterhood of the Traveling Pants co-stars Amber Tamblyn and Alexis Bledel. Fun!
