Khloe Kardashian And French Montana Spotted on Vacation...

 It seems the exes maybe back together as they were pictured over the weekend having fun,  jet skiing with BFF Malika and French's homie, Chinx

However, our sources tell us French greeted Khloe with a bouquet of red roses when she arrived at the resort over the weekend.

No one's saying they're totally back on yet -- but as one source put it, "I wouldn't be surprised if they fall back into old habits" while they're down there. See another photo after the cut...
