The fun event featured a photo booth that celebrity guests couldn't get enough of, as evidenced by the pictures that they all shared on social media.

Kardashian's uber-sexy, cleavage-baring dress definitely stole the show. The KKW Beauty founder looked absolutely stunning as she posed with her husband and the other A-listers there, which continued her recent streak of pushing the envelope when it comes to showing skin on social media.

#ad Little update for you guys. I’m on Day 9 of my Shake It Baby program from @flattummyco and I’m actually feeling so good. We had a massive Christmas this year and between my Mom's party, Christmas and New Years… I felt like it was impossible to fit in my regular work outs and eat healthy. But this program is giving me a kick in the right direction that I need. These meal replacement shakes are so good and it’s helping me get my tummy back to flat in the new year. The results I’m seeing and feeling are amazing and I’m so excited for the next few weeks. Because they’re all about getting women back on track… they’ve got a 20% off sale going on right now if you want to start 2018 off right… trust me, you’re going to want to check them out.

Yep, then I made myself a smoothie
