She may have just gotten engaged, but Kim Kardashian is already in a bridal state of mind.

The sultry mom showed off her killer curves and ample assets in a white lace bustier and tight skirt. She looked absolutely sinful at her birthday celebration on Friday night in Las Vegas. Her new fiance Kanye West wore a matching red lace blazer. He seemed smitten with the reality darling, caught staring at her lovingly several times throughout the night.

Kim was also joined by her family, including mom Kris Jenner and sisters Kourtney and Khloe, who wore sexy all-black getups. Kourtney's boyfriend Scott Disick -- aka the duke of Vegas -- family friend Robin Antin and Kim's gal pals Naya Rivera and Blac Chyna were also on hand for the party. The family attended Kanye's concert at the MGM Grand before heading to the Venetian.

While the 33rd birthday bash at Tao nightclub was extravagant, Kim's actual birthday celebration is unmatched. Kanye rented AT&T Park, the home of the San Francisco Giants, to propose to the mother of his newborn baby girl, on Oct. 21. All the booze and beats in the world can't beat that!
