SPOTTED: Gossip Girl's Leighton Meester's Very Public PDA

Leighton Meester, aka Blaire Waldorf of Gossip Girl, was seen tonight at a private screening at the Tribeca Grand Hotel of the new movie Sex Drive putting on quite a sexy show of her own.

According to multiple sources at the event, Meester was “making out” non-stop with her date.

It was a “good, three to four minute make-out session in a intimate setting,” which includes stars from the movie Seth Green and James Mardsen.

As they say, get a room.  She was in a hotel afterall.
