It turned out to be quite the party as the whole Kardashian Klan turned up to usher in the rapper's 30th birthday.
Khloe along with sisters Kylie, Kim and mom, Kris, attended the suave soiree, dressed to the nine and posing for a range of selfless that got posted to Instragram right quick.
Khloe and French were and item for 6 months following the end of Khloe's marriage to basketballer, Lamar Odom.
Over the last few days, reports have been coming in hinting that the two might be back together and if his birthday is anything to go by, we'd say there's plenty of evidence to say it's true.

French replied in kind, saying he had a 'legendary night'.
The pair celebrated Khloe's own 30th back in June, during which French gave her white Jeep Wrangler worth £49,000.
