Oh, what a night!
Nicole "Snooki" Polizzi enjoyed a night out without baby Lorenzo Tuesday, linking up with Jersey Shore
costar Deena Cortese to toast the end of their show at West Hollywood hotspot Bootsy Bellows. But the ladies had some random company, in the form of Real Housewives of Beverly Hills
star Kyle Richards and her friend, Faye Resnick.
The foursome – there with a few other pals – arrived around 11:50 p.m. and went to the club's VIP room before hitting the dance floor – hard. The group busted moves to songs like James Brown's "Get Up (I Feel Like Being a) Sex Machine" and Jackson 5's "I Want You Back" while sipping vodka cocktails (Richards abstained from alcohol).
Once Cortese spotted club owner David Arquette, she told him, "You need to take a picture with the two meatballs. You're the sausage!" So the actor obliged, posing for a shot with Cortese and Polizzi, later seeking them out to entertain them with his Keith Richards marionette.
Resnick and Richards left around 12:30 a.m., at which time Dancing with the Stars
pro Derek Hough
came over to the Jersey Shore
stars to say hello – just as Cortese took a tumble backward and broke a few glasses at her table.
At 1 a.m., Cortese and Polizzi left the VIP room and headed for the main part of the club to enjoy some house music, and ran into Glee
star Amber Riley, who joined them at a table for a bit.
Meanwhile, Julianne Hough
arrived around 1:15 a.m. (sans boyfriend Ryan Seacrest
) and immediately hit the dance floor, grooving to the Spice Girls's "Wannabe" and AC/DC's "Back in Black." But when the DJ spun Dion's classic "Runaround Sue," Derek joined Julianne on the dance floor and the two broke out into a full-on choreographed routine. The dance floor cleared as people cheered them on – especially when Derek fell into the splits (more than once!). Julianne left not long after, around 1:40 a.m., and Cortese and Polizzi slipped out a few minutes (and cocktails) later. – Jennifer Garcia
