The Victoria’s Secret model held court outside in a cabana Saturday for the dayclub opening, but the party hardly stopped there!The good looking gang proceeded to hit up Marquee club later Saturday night where sources tell us Alessandra (looking breathtaking in a gold cut out mini dress), Jamie, and Adrien had one big dance party! The group overlooked DJ Eric Morillo and all seemed in good spirits as they celebrated the night away.

Check out all the Sin City fun in our gallery!

Spotted on the red carpet were 90210‘s AnnaLynne McCord, 21, Heroes‘ Kristen Bell, 28, and Brea Grant, 27, fired from the sequel to Twilight‘s Taylor Lautner, 16, Gabrielle Union, 36 (*ahem* Young Hollywood?), Channing Tatum‘s fiancee Jenna Dewan, 28, Entourage‘s Kevin Connolly, 34, and Jerry Ferrara, 29, Taye Diggs, 37 (did he come with Gabrielle?), a bespectacled Matt Dallas, 26, Jennifer Morrison, 29, Sanaa Lathan, 37, Lakeview Terrace‘s Kerry Washington, 31, and former Dirty Sexy Money actress Samaire Armstrong, 28.

Celebrities designed their own red carpet jewelry and shoes for the event. The pieces will be sold to the highest bidders at a charity auction at a Los Angeles art gallery on May 28.

Everyone seemed to arrive with some taste, with a few exceptions.

That giant braid wrapped around Samaire’s head wasn’t flattering.

Kristen Bell rocked some trousers that might have looked more appropriate at a retirement community’s dance recital.

And Taylor Lautner seems to be taking his firing from the upcoming Twilight sequel as an excuse to get a Saturday Night Fever re-make going.
