Happy 40th birthday, Snoop Dogg! Today, Oct. 19, the Doggfather turns the big 4-0! It seems like just yesterday that a 23-year-old Snoop was rolling up in a pimped-out convertible rapping about "sippin' on gin and juice" with his fellow Death Row crony Dr. Dre.

To celebrate his momentous birthday, Snoop Dogg, his family and his closest friends gathered at the Rolling Stone Lounge in Hollywood, Calif. for some festivities. Some of the guests that hit up the suaree were Dr. Dre, Dre's step brother and Snoop's good friend Warren G, P-Funk member/James Brown collaborator Bootsy Collins, and vocal powerhouse Chaka Khan.

At the party, Snoop stood next to his wife Shante as he was presented with a very special, personalized birthday cake. The cake was actually made up of two cakes -- one was a '4' and the other was a '0' (to make a '40,' duh!), but instead of having a hole in the middle of the '0' cake, it was replaced with a confection version of a bottle of Colt 45. Snoop still knows how to drink malt liquor like a champ, apparently!
