"Jersey Shore" castmember Jenni "JWoww" Farley celebrated her 23rd birthday party with her boyfriend Tom Lippolis at Moon Nightclub in Las Vegas on Saturday wearing a low-cut black dress that showed off her ample bosom.

Meanwhile, fellow castmates Nicole "Snooki" Polizzi and Vinny Guadagnino were caught up in a terrifying incident in New York City on Saturday night after a glass roof collapsed on them in a Manhattan building. The glass ceiling of the atrium caved in under the weight of ice and snow on the roof, sending dangerous shards into the lobby below.

Snooki took to her Twitter page to tell fans of the frightening accident. She wrote, "Omg roof just collapsed. We thought the DJ was beatin' the beat hardcore but nope, the roof couldn't handle Snooki and Vin."
