Ch-ch-changes!

Blac Chyna threw on a braided blonde wig and partied it up with a new mystery man last night, and she straight up told paparazzi that they're dating! She could have been joking just to make a play on Rob Kardashian's recent romance drama, in which reality star Mehgan James planted stories she's his girlfriend just for publicity. Still, this guy's hot so it would make sense if they're getting cozy.

The video vixen and Arthur George sock designer aren't currently together, but he's still hoping they manage to work things out and raise daughter Dream as a family.

"Rob still loves Chyna and ideally wants to be with her and her alone. He hates how they fight but in the end she‘s the best thing that’s ever happened to him. He misses her dearly even though she doesn’t want to be with him. Rob is still hoping they can make things work," a source dished to Hollywood Life.

"He’s terrified that Chyna will flip and dump him for good is she thinks he’s dating some other chick. He’s assured her that he isn’t hooking up with anyone and just wants to be a family man with Dream," the source added.

BC might want to consider getting back with Kimmy K's little bro, because her fame is going to fade fast otherwise. Nobody cares about her unless she's part of the K clan drama!
