Possible Couple Alert: Drew Barrymore & Chace Crawford

A couple of swingin' singles, Drew Barrymore and Chace Crawford of Gossip Girl fame, are now dating, Perez Hilton is reporting this morning.

"It's early on but they're definitely dating," an insider said.

The pair hit up the Saturday Night Live after-party together this past weekend, and were out and about again on Monday night!

Drew Barrymore and Chace Crawford were at the Kings of Leon concert in New York City and they made no attempt at hiding their relationship.

Multiple eyewitnesses say they were making out in plain view!

Chace's last relationship of note was with Carrie Underwood, but they broke up via text message. Like, OMG. Drew broke up with Justin Long in July.

UPDATE: Now Us Weekly is reporting that she actually made out with Ed Westwick - Chace's BFF and Gossip Girl co-star. Apparently Crawford was there, as they go everywhere together, but Drew was all over Ed. Nice work, Perez. Jackass.
