Kimye just could not keep their hands off each other sharing kisses in front of photographers while John and his supermodel wife Chrissy Teigen posed like normal people.
And if that wasn't enough, Kim donned a revealing v-neck and heels designed by her husband, while Kanye dressed up in white and black formal wear. Both wore Balmain for the occasion, which is only fitting given that they are both the new faces for the fashion house.
Not to be outdone, Chrissy did bring the sex appeal in a similarly low-cut dress with slits up to there! After all, she was the host of the event, which also marked the 10th anniversary of John's debut album Get Lifted. Other notable guests included Robert De Niro, Katie Couric, Michael Strahan, Padma Lakshmi, Jonathan Cheban and Q-Tip, who DJ'd the party.
After dinner, partygoers headed upstairs for a private party at CATCH Roof, where executive pastry chef Thiago Silva presented John with an oversized grand piano-shaped cake.
Kim and Chrissy aren't the only ones showing off cleavage. Watch the video below to see who else is showing off their assets.
