The Real Housewives of New York's Team Blonde added a new member Sunday when Sonja Morgan and Taylor Armstrong collided at the CÎROC Cabana Club launch in Sag Harbor.

Armstrong, who flew in from LA for the opening weekend of the nine-bedroom gated party house in Noyac, left the next morning to spend the fourth with her daughter, but she made the most of her night, dancing with Dina Lohan (who kept her blackout shades on the whole time) and dining at Georgica with Morgan later that night.

"What I do like about the Hamptons is you can get on that Long Island Distress-way last minute with no plans and end up entertaining your friends from Hollywood," Morgan said.

Rev Run jumped up to the DJ booth for an impromptu set, emceeing as DJ Ruckus and Jesse Marco provided the tunes.

Also in attendance at the OK Magazine-sponsored party was Twilight's Kellan Lutz, who immediately stripped off his shirt (thank you!) to show off his athleticism, rallying on the house's tennis court before starting a volleyball game in the pool. Georgica's executive chef Seth Levine got soaked, but Kellan's crew (including manager Ryan Daly) stayed dry in the sand on the NY Lounge Decor daybeds.

BET's Julissa Bermudez, Rick and Kathy Hilton, Jonathan Cheban, Al Harrington, Jessica Hart and polo hottie Starvos Niachos also mingled outside, braving the drizzle and avoiding the... er... gifts that someone's cute bulldog left in the sand.
