Kim and Khloe Kardashian returned home from London on Sunday evening, but within a matter of hours they were back out the door and heading to French Montana's birthday party! And after checking out all the party pics the girls posted from the soiree, it's pretty safe to say that the rapper is definitely back with Khloe...

The bash was at supperclub LA in Hollywood, and while Kanye West was nowhere to be seen, momager Kris Jenner was there with new boy toy Corey Gamble. PMK and her beau flew to Vegas on Friday for Kris' 59th bday celebration at 1 OAK, so it's been a busy weekend for the reality TV family!

Kim wore a tight black turtleneck while Khloe wore a dress with a slit that was well past her panty line (was she even wearing any?!). Kylie tried to steal the show in an Ariana Grande-inspired hairdo, but the color is so blah, we think her locks would have been better up in a bun.

In addition to snapshots from inside the Ciroc-sponsored party, Khloe posted a shot of the duo on a beach and wrote, "Happy birthday baby boy! In only a short amount of time we have created timeless memories. Happy birthday to a man who genuinely lives life to its fullest. What's understood doesn't need to be explained @frenchmontana I can't wait to celebrate life with you tonight! You deserve it!!"

While French wasn't too chatty with photographers after his party, it definitely looks like he had a good time:
