Victoria's Secret model Alessandra Ambrosio took the plunge - as in plunging neckline - at the Marquee Dayclub's grand opening in Las Vegas Friday. The new day club is one of three pool areas at the Cosmopolitan Las Vegas hotel & casino.

But despite Alessandra bringing her two-year-old daughter Anja along for the festivities, the club is strictly adults-only and will be open during sunny days during the spring and summer.

Marquee features eight cabanas with flat screen televisions and full food & beverage service. Each cabana also boasts its own dipping pool. Three-story bungalow lofts with overnight accommodations are also spread out around the club, with a party deck up on top.

The Brazilian beauty also celebrated her birthday a little early while at the club - she turns 30 on Monday, April 11th.
