Chris Brown and Rihanna are dating. And you know what couples who are dating do? Show each other affection. No, we don't like it, but it's happening.

Following the 2013 Grammys, RiRi and Breezy attended an after party at the Supperclub in Hollywood and seem to have forgotten all about that fateful incident that happened before the same award show four years prior. Bad habits die hard, we suppose... [Sigh]

An "observer" told Ace Showbiz that Rihanna sat on Chris Brown's lap while gettin' her drink and smoke on. The same insider also divulged that the two got "very affectionate." It wasn't like the two lovebirds were hiding their feelings towards each other before this party either. They were pictured getting cozy during the Grammy Awards as well. Yes, we just collectively threw up in our mouths a little bit, but they are dating and they seem to think it's a good idea to give a good PDA show.
