This has got to be one of the most ambitious business moves that we’ve seen in a while by a couple of hip-hop big wigs. The CEOs of Cash Money Records, Bryan “Baby” Williams and Ronald “Slim” Williams have just launched a new venture called Bronald Oil & Gas, which focuses on identifying and using oil reserves.

The Williams brothers will be putting their new venture into actions in areas such as Osage County, Oklahoma, Texas, Louisiana, Florida, and unidentified Central America.

We hear about hip-hop figures investing in restaurants and professional teams, but never have seen any of them make a move like this. In case you guys don’t know, finding oil is a big lucrative business and this could lead to the Williams brothers becoming wealthier than Jay-Z, Russell Simmons, 50 Cent, and Diddy combined.

Jay Sean may be new to us, but from what we hear, he’s been doing the damn thing oveseas since 2005! His first U.S. single “Down” (featuring labelmate Lil Wayne) is currently sitting at #2 on the Billboard Hot 100, after taking the Black Eyed Peas‘ spot and spending a week at the #1 position.

Jay Sean (born Kamalijit Singh Jhooti) is a British Indian Pop/R&B singer/songwriter, born in West London, England to parents who migrated to the U.K. from Punjab, India. He started his music career overseas under Virgin Records and he signed to Cash Money Records over here in the U.S. back in 2008.

Jay and his bosses Birdman and Slim from Cash Money hosted a listening session last night at New York City’s greenhouse nightclub. Executives and artists from Universal Republic (Cash Money’s parent label). R&B singer/songwriter Melanie Fiona was also on hand to help celebrate her labelmate’s recent success of being the first Cash Money artist to reach #1 on the Billboard Hot 100 this year.

Be on the look out for Sean’s U.S. debut album, All or Nothing, set to be released November 2009.
