Veteran rapper Slick Rick celebrated his 50th birthday onstage with Nas on Friday (09Jan15) at a special concert in Brooklyn, New York.

The Brit, real name Richard Walters, invited fans to attend the show at Brooklyn Bowl to help him mark the age milestone and delighted the crowd by revisiting old hits, including La Di Da Di.

He then introduced Nas to the stage for a surprise collaboration on his classic Children's Story.

Slick Rick will actually turn 50 on Wednesday (14Jan15).
