Last night, Slick Rick was booed during his halftime performance at Barclays Center.

The Ruler took the stage midway through the New York Knicks versus Brooklyn Nets game, beginning his performance by shouting out Jay-Z and Beyonce who were watching the set.

But after running through “Hey Young World” and segueing into “Mona Lisa,” the eyepatch-sporting veteran hit a wall when the audience turned on him, booing through the end of the performance.
