Rihanna's "good friend" Matt Kemp threw her a great 22nd birthday party. E! reports that there were flowers, Sprinkles cupcakes, tiki torches in the pool, engraved bottles of Ace of Spades, a Jamaican chef, and more.

There were 40 of Rihanna's friends and some of Matt's baseball friends in attendance.

Matt brought out a cake decorated with Rihanna's tattoos (she has over 13) and gave her a custom diamond necklace. Matt is quite the planner. The LA Dodger reportedly had the weekend planned out, which began with a party bus to an Arizona nightclub on Friday and ended with a brunch on Sunday. Matt is currently in Arizona for spring training.

Matt and Rihanna make such a hot couple. They haven't even been together very long and Matt went all out?! That says a lot. Happy bday, Riri!
