Ben Affleck has been dating singer/model Katie Cherry for a couple of months. But it appears that Drake's dad, Dennis Graham, may have stolen her from the Batman actor.

Just a few months ago, Katie and Ben were all over Hollywood together. Here's a recent video, explaining the couple's relationship:

And the two are still believed to be in a relationship. But that may be coming to an end soon.

That's because last night, Katie Cherry was spotted out partying with Drake's dad Dennis Graham at Warwick Nightclub in West Hollywood. 

The two arrived at the same time, and Dennis is seen trailing behind Katie as she smiles for the camera. 

And Drake's father has a very "I got caught" look on his face
