All that time in the gym is paying off!
Khloe Kardashian put her bangin' booty on display during an appearance at 1 Oak in Las Vegas on Friday night, stepping out in a black dress with sheer cutouts that left little to the imagination.
The "Keeping Up With The Kardashians" star paired her figure-hugging ensemble with black pumps and a slicked back 'do.
Check out that perky derriere from the side!
The 30-year-old beauty clearly is proud of her famous asset, and she's worked hard to tone up her enviable bod.
Not only does she hit the gym with celebrity trainer Gunnar Peterson, but she recently spilled the secret to getting a perfect derrierre.
On a recent episode of "Keeping Up with the Kardashians," Khloe got her butt lasered as sisters Kim Kardashian and Kendall Jenner watched!
It might just be jealousy, but Kim even threw some shade at her sister's big booty.
"Khlo, I got you a dress ... I see like your a-- is so huge, I just don't know if it will fit your a--," Kim told a horrified Khloe. "Do I give it to Kylie or do I give it to you?"
"What do you think we're doing?" Khloe responded. "We're trying to make it smaller!"
