Biz Markie is getting a grand sendoff from his famous friends and family … his celebration of life is set for Monday in New York City.

Al Sharpton will deliver the eulogy and celebs like Fat Joe, LL Cool J, Papoose, Big Daddy Kane, Al B. Sure! and Leland Robinson will be front and center to pay their respects to the trailblazing rapper.

It sounds like Biz will have an open casket … we’re told he will be dressed in a custom outfit designed by Harlem fashion icon Dapper Dan. Biz, of course, was one of Dapper Dan’s biggest supporters when their careers were both getting off the ground.

There’s a private family viewing set for Monday from 11 AM to 1 PM ET and the funeral service is scheduled to begin at 1:30 PM and run until 3:30 PM. and BET will be live streaming the celebration of life starting at 2 PM.

The “Just A Friend” rapper died earlier this month following a series of complications from diabetes.
