After experiencing a huge surprise with Kanye West’s marriage proposal last week, Kim Kardashian held a birthday/engagement party this past weekend in Las Vegas at Tao nightclub.

The all-star event started late Friday evening (Oct. 25) and lasted into early Saturday morning (Oct. 26), according to E! News. The 31-year-old celebutant, and mother of North West, dazzled in an all-white gown, which showed off her curvaceous figure and cleavage -- she can thank her new baby for that!

Kim completed the look with the only accessory needed for that gown -- the rock. Wowsers! Her 15-carat diamond engagement ring is more than just a rock, it’s a mountain. If diamonds are a girl’s best friend, then Kimmy’s sparkler is her BFF.

Meanwhile, her fiancé, Kanye, was dressed in a red blazer with a charcoal-colored T-shirt, black pants and dress shoes.

Among the celebrities in attendance were Kim’s mom, Kris Jenner, and her sisters Khloe and Kourtney, as well as their hubbies, Lamar Odom and Scott Disick, respectively.

Kim also took photos with several party revelers, including her gal pals Naya Rivera, Blac Chyna (whose boo is rapper Tyga) and Pussycat Dolls founder Robin Antin.

Later in the night, Kim did receive a giant birthday cake with sparklers. "Thank you for celebrating my 33rd bday with me!" she told partygoers.

According to E! News, when Kim was asked if she would take the surname West, she responded yes, and that her name would be Kim Kardashian West.

Congratulations to Kim and Kanye. We wish them the best. Please send us an invitation to the wedding.
