Is Khloe Kardashian Dating French Montana? -- Stip Club, House-Hunting, BANGING?

Khloe Kardashian and rapper French Montana have been spending a lot of time together ... the kind of time that leads people to ask, "Are they banging?"

We're told French is on the hunt for a new pad and took Khloe along to check one out -- a 4,800 sq. ft. Hollywood Hills home that rents for $29,000/month. It's a 4 bedroom, 4 bath house with a wine and cigar cellar, a sauna, and screening room.

And, they hit up Pink Rhino in Phoenix this weekend where French was a promoted guest. We're told the pair and their entourage went through 10 bottles (on the house, of course) and shelled out $7K on girls.
