Her birthday itself brought a lavish proposal from her husband-to-be Kanye West, but the celebration was far from over as Kim Kardashian held her birthday party at TAO nightclub in Vegas on Friday (October 25).

Showing off her amazing post-baby body, the 33-year-old reality star wore a lacy white party dress that showed ample cleavage with a matching clutch and heels.

In attendance at the bash were her fiancée, sisters Khloe and Kourtney, and her newly-separated mom, Kris Jenner. Homebody Bruce Jenner was nowhere to be found.

Sharing a gorgeous photo of herself and her gals, Kim tweeted, "Let the bday festivities begin Vega$ @nayarivera @kourtneykardash @blacchyna @robinantin."
