Diddy turns 42 years young today. L'haim!

The music mogul has not only had his hand in plenty of hip-hop's evolution and history, including Biggie, Lil Kim and Mase, he also has a philanthropic side, most recently donating enough money to the Harlem Boys & Girls Club to help keep it from shutting down.

And, not only that, but the multidimensional Ciroc boy opened his first Sean John store in Macy's New York last month. On the music tip, Puff appears on Pusha T's "Changing of the Guards" track which was released  earlier this week.

Happy birthday, Diddy!
