'Gossip Girl' finale: Will Blair finally put Little J in her place?

gossip-girl-blair-jenny-last-tango-then-paris.jpgThe long-awaited "Gossip Girl" Season 3 finale, "Last Tango, Then Paris," has finally arrived -- and from the looks of our sneak peek preview clips, it promises to be an OMG! conclusion to a roller coaster of a season.

Little J ( Taylor Momsen) sets off a bomb threatening to destroy Serena ( Blake Lively) and Nate's ( Chace Crawford) on-again-off-again relationship once and for all ... but this time big brother Dan ( Penn Badgley) gets caught in the shrapnel. Basically, Serena and Dan (who's still in a relationship with Vanessa) have a little (accidental?) slumber party, and Jenny snaps an incriminating pic -- which she promptly forwards to Gossip Girl for a text blast.

Should have thought twice before hitting send, Little J. Blair the "itch" is back, and she's not about to let this one slide. Will Jenny endure the ultimate Waldorf wrath?

This episode also sets up Serena, Blair ( Leighton Meester) and Chuck's ( Ed Westwick) summer trip to Paris, which is where Season 4 will kick off.

Check out the trailer and sneak peek clips that preview Jenny's possible demise at the hands of our favorite "itch."
