Gigi Hadid -- Joe Jonas Is a Real Dog ... Lover (TMZ TV)

Gigi Hadid spent a day hanging out with Joe Jonas ... which had people wondering if they're boning now! She’s denying they’re anything more than friends -- but there's a few cute puppies that might say otherwise.

That is, if dogs could talk -- and wouldn't that be awesome?? Anyway, since the pooches ain't talking ... we'll ask the TMZ Hollywood tour guide who kinda spotted 'em out.
