Watch Rihanna teach Jim Parsons how to take the perfect selfie

Rihanna, you're the reason social media was invented. (James Franco is the other one.)

The singer, whose scuffles with Instagram have been well documented, has mastered the art of the selfie (sorry, Kim, but she has).

Here, she teaches The Big Bang Theory's Jim Parsons -- her costar in the animated flick Home -- the art of taking a great one. "You have to find your angle," she tells him.



In other Riri news, the singer is throwing her first annual Diamond Ball in L.A. on Dec. 11, to raise money for her Clara Lionel Foundation (CLF).

Jimmy Kimmel is hosting. Oh yeah, and Brad Pitt is stopping by. Wait, you don't have plans that night? Good news -- there are 600 guests total and if you can afford it, you too can hear an intimate performance by Rihanna, accompanied by a live orchestra, while rubbing elbows with the A-list. Have fun!
