All of us at Gossip Girl Insider would like to wish a happy birthday to cast member Penn Badgley, who turns 23 today on this first day of November.

We hear that Penn may be getting engaged soon (and we all know to whom). That would be the cutest thing ever for the Gossip Girl lovebirds.

Either way, we love him as Dan Humphrey and hope his special day rocks ...

Penn out Thursday at the Rock and Roll Hall of Fame party in NYC.

In honor of the big day, as we do for all our cast members, here's a little tribute of Penn Badgley pictures, one for each of his 23 years. Happy birthday, Penn!
