Half of Hollywood was at The Nice Guy Friday night -- even some less common faces like Drake!

Kourtney Kardashian showed off some side-boob in a black jumpsuit -- flying solo at the club. A pregnant Chrissy Teigen wasn't wearing maternity wear, that's for sure! The sexy supermodel showed off her legs in thigh-high boots and short shorts. Hubby John Legend is certainly still smitten, showing the paparazzi how much he loves his wife with a make-out sesh at the valet.

Aussie Cody Simpson was there alone; stylist-to-the-stars Rachel Zoe, and former Destiny's Child star Kelly Rowland. What a night!
