Gossip Girls heartbreaker, Chace Crawford, no sooner broke up with sultry songbird Carrie Underwood via text messaging than he was out "snuggling" with brand spanking new costar Michelle Trachenberg at a tres chic SoHo nightspot!

"It was completely mutual," crestfallen Carrie confided to The New York Daily News. "It just didn't work."

No sooner said than sent, Chace was downtown with hottie Michelle at the exclusive club, Upstairs.

Insiders told Page Six they were "flirting heavily" and that he was "all over her".

Talk about staying in sync! Maybe this Gossip Boy should change his name to Cad Crawford?
