Khloe Kardashian: Date Night with French Montana ... At the Strip Joint

Khloe Kardashian could have a future at the L.A. County Fair as a professional juggler, because she hikes with a husband, sometimes dates a basketball player, and hangs with her ex-boyfriend ... all at the same time.

Khloe and ex-bf French Montana hit up Ace of Diamonds strip club Monday night in L.A. It's interesting ... Ace of Diamonds may have caused a rift in Khloe's relationship with James Harden after he partied there last month ... she seemed none too pleased he was there, posting on Instagram the same night, "Stay away from people who make you feel like you are hard to love."

We haven't seen Khloe and James together for a while, but they all seem to come back ... eventually.
