On November 15, E-40 will be celebrating his 40th birthday with a birthday party inside Caesar’s Forum Shops at The Poetry Nightclub. In preparation for the bash, the Vallejo, California born rapper announced his burgeoning health drink, 40 Water.

Although his rap moniker reportedly comes from an ability in his youth to “empty a 40 ounce bottle of malt liquor,” according to The Ego Trip Book of Rap Lists, E-40 will collaborate with the New York-based company on 40 Water, the flavor named after one of Earl Stevens’ many nicknames. “Rapping brought me into the entertainment game, once I got in my eyes got bigger. As a business man I get the best of both worlds and the privileges of working and reaping the benefits at the best time in my career,” said 40, who also owns several franchise locations of Fat Burger and  Wingstop.

Along with 40 years of life, this  benchmark milestone marks 20 years “in the game” for 40.  The rapper has released official album’s since 1993’s Federal, but Bay area  fans have heralded 40’s underground work dating back to 1987 and 1988. Most recently, 40 served as announcer to The BET Awards. 2006’s gold-certified My Ghetto Report Card. The latest release will be followed by an early 2008 The Ball Street Journal through Sik Wid It/BME/Reprise Records.

Gearing up for the event, 40 said,  “I really felt it was about that time again where I brought all of my friends and fam-bam together to have one big pow-wow and toast it up in the air for several occasions.” There is no word as of yet what “40 Water” will taste like.
