Happy Birthday C Breezy!

Think Like a Man actor and singer Chris Brown rang in 23-years-old Saturday on Cinco De Mayo, and former girlfriend Rihanna didn't forget to wish her "Turn Up the Music" partner a happy birthday! 

RiRi, who also collaborated with Brown on the track "Birthday Cake" (how appropriate!), tweeted her former BF a simple: "Happy Birthday @chrisbrown."

So, how is Brown celebrating 23?

The singer hit up Las Palmas last night in Hollywood with current girlfriend Karrueche Tran, and took to his own Twitter to tweet "GREEN GOBLIN!" along with a pic of a neon green and studded backpack.

Hmm, possibly B-day gift from Karrueche?! Very studly. The backpack, that is.
