Here's sports reporter Holly Sonders hittin' the strip club with notorious high-stakes gambler Vegas Dave ... begging the question -- you guys a couple or what?!
Sonders and VD have been pretty tight recently -- she's been promoting him like crazy on social media ... the assumption is that she was doing paid promo work for the guy.
But, Wednesday night Holly and Dave were holding hands on the way into Crazy Girls in Hollywood ... and inside she was kissing the guy on the face while throwing stacks of cash.
