Rihanna and Chris Brown Laugh & Cuddle Up Courtside on Christmas (PHOTOS)

It’s officially official. Chris Brown and Rihanna are back together!

We’ve seen all the twitpics and the “spy” photos of them partying together in the club … and after all the rumors, denials and hints (that really weren’t “hints” at all), Chrianna is officially back on.

The on-again, off-again, and now back on-again couple were spotted laughing and cuddling up courtside last night at the New York Knicks vs. Los Angeles Lakers Christmas game at the Staples Center in L.A. — marking their first public appearance in years as a real couple.

The apparently happy couple (sidebar: please don’t take their joy away from them right now) even took a few photos with rapper Game‘s son Harlem.

Game tweeted: “Uh oh @harlemcarontaylor thought he had @badgalriri on lock….. @fuckyopictures want his girl back ha ha ha….. Guess he’ll just have to settle for @ritaora now lol.”

Check out over a dozen pics of Chris and RiRi boo’d up at the game below:
