It was a wild weekend in Las Vegas -- with crazy parties for stars like Kellan Lutz, Dane Cook, The Situation and his "Jersey Shore" cohorts Snooki, Sammi and Deena!
The Situation kicked off the weekend by first hitting up the Sugar Factory and Sugar Factory American Brasserie at Paris Las Vegas in the afternoon on Saturday, where he was seen feeding candy to Marcy Depena -- a Las Vegas local who was by his side all night when he went to Chateau Nightclub too!
Other "Shore" cast members in town included Snooki (who partied at LAX on Saturday with her boyfriend and her father) and Sammi and Deena -- who hit up Sugar Factory and Chateau on Sunday for Sammi's 24th birthday bash. "Keeping Up with the Kardashians" star Scott Disick was there as well.
Kellan Lutz and Dane Cook also celebrated their birthdays in Sin City -- as the bulky "Twilight" star had his 26th b-day bash at Pure on Saturday while his brother also had his bachelor party. Dane, who turns 39 on the 18th, got his party on Saturday at TAO nightclub at The Ventian.
Paris Hilton and Juliette Lewis hit the town as well on Saturday for a Strokes concert at The Cosmopolitan, while Derek Hough was at the Palms Resort & Casino teaching an exclusive dance
lesson to 15 students from various Clark County School District middle schools and high schools.
