OMFG. Last night at Webster Hall, the main event proved not to be the performance by Kings of Leon but the intense makeout sesh we witnessed between Drew Barrymore and Ed Westwick, a.k.a. Chuck Bass. We’d seen the pictures of Chace Crawford and Barrymore leaving the Saturday Night Live after-party the other night, but we never imagined it was a ruse to cover up her steamy affair with Chuck Bass.

Following last night’s show, Westwick, wearing leather pants and pointed shoes, accompanied Barrymore to the after-party at Bowery Electric where the pair continued their PDA. Barrymore even straddled Bass — um, we mean Westwick — in a move not dissimilar to that time Serena did it with Nate on the bar. To be honest, the whole thing kind of hurt our eyes a bit, not least because at 33, Drew is definitely the Catharine to 21-year-old Westwick’s Marcus. Needless to say, he could barely conceal his smug satisfaction all night — and left wearing the same half-smile Chuck did after he bagged Blair that fateful night in season one.
