She's bouncing back and she's proud of it!

Kim Kardashian returned to the red carpet last night for the first time since giving birth for a paid appearance at Hakkasan night club in Las Vegas, and the reality star showed off her impressive weight loss in a black and gold Balmain gown. Hot mama! The mother-of-two previously revealed that she had already lost 42 lbs, but she had another 28 lbs to go before reaching her goal weight.

“This time I think weight has come off quicker than last time because I kind of learned how to eat better. Last time I worked out a little bit harder. This time I’m eating differently. I’m doing the Atkins diet and I’m so militant about it that I just started working really hard and I think the mix of the two will really help out this last 20 pounds fly off. I’m praying," she told E! News at the event.

Her night in Sin City comes on the heels of her family ski trip to Vail, and we seriously don't know when this girl rests. Her schedule is more packed than the President!
