That WAS a happy birthday! At least for Kim and Kanye it was! The Kardashian's BFF Jonathan Cheban celebrated his 45th birthday party at Nobu Malibu Wednesday night and literally EVERYONE was there ... oh wait -- not Khloe! Poor Khloe was M.I.A. for @foodgod's b'day. She probably doesn't feel like celebrating ...

But the party went on without her and Kim and Kanye stole the show, as usual. Kim was in head-to-toe denim, with a cropped patchwork halter. Kanye colored his hair white and red and wore his usual Desert Storm camo look. The couple shared an intimate kiss as they left and Ye grabbed a little booty as Kim turned around :)

Momager Kris Jenner was with date Corey Gamble (can you believe they're still together?!) and Scott and Kourtney were each other's dates for the evening!!! Watch out, Sofia!
