Sean Divine Jacobs (born November 9, 1976), better known as Sheek Louch (also known as Donnie Def Jam and "Donnie G"), is a rapper and member of The LOX and founder of D-Block Records, along with Styles P and Jadakiss.
At around the age of 12, he was inspired to rhyme by his friend Jason Phillips (Jadakiss). He and Jason would later form The LOX with Styles P. Mary J. Blige "discovered" the trio, and they would soon be signed to Sean Combs's Bad Boy Records. Their first album, Money, Power & Respect, was released on January 13, 1998.
Sheek and his fellow LOX members later parted ways with Bad Boy Records, and joined the Ruff Ryders group, which included DMX. Their second album, We Are the Streets, was released on January 25, 2000. Meanwhile, Sheek, an aspiring entrepreneur, began working on their D-Block brand, building a studio, and looking for new talent to join their roster. He also opened a D-Block car wash and D-Block "fitteds" around the same time.
He has worked somewhat prolifically with Ghostface Killah. They collaborated on a joint album titled Wu Block featuring members of Wu-Tang Clan and D-Block after drawing inspiration from one another while touring and recording.
