Lance Bass, Tinsley Mortimer, Olivia Palmero, Kelly Bensimon, Julie Henderson, Russel Simmons, Ciara, Swizz Beats, and Nicky Hilton were among the red carpet guests at the grand opening of Lavo on The Upper East Side. And, it's complete with a dance floor.  What could be better?  It seems that New York nightlife has a new superstar straight out of the Vegas desert.
