Partygoers lining up outside Hotel Gansevoort for Nylon's 8th anniversary rooftop bash Wednesday night were treated to thongs, er, throngs of sign-wielding and bucket-banging Meatpacking District residents none-too-thrilled with the hotel's plan to put up a billboard in their 'hood.

Once inside, though, it took revelers roughly two SoCo-with-limes and an hourlong "gifting suite" — open to all attendees — to forget about the silly little protest on the street some 14 floors below. ("What's the big deal about a billboard? Look at these jeans!")

Christina Aguilera, the evening's host, eventually showed, as did Jamie-Lynn Sigler and Lance Bass, who sang-along to Bass' former boy-band boy Justin Timberlake's "Sexy Back."

Other FBNY notables: Alan Cumming, Run-D.M.C.'s Darryl "D.M.C." McDaniels, Eve, Page Sixer Corynne Steindler with her sister, and Daily News Gatecrasher Ben Widdicome sporting an impressive Boris Becker beard.
