In fact, he made it pretty clear he's not even involved with anyone.
Chris posted screen shots of an article claiming he was spotted shopping for engagement rings with a long time girlfriend along with a "picture of the girl" that was actually an emoji and stick figure drawing he made on his phone. Hilarious! He probably doesn't want anyone thinking he's off the market if he is in fact available.
