Watch 50 Cent Perform At New Kids On The Block’s Madison Square Garden Concert

Last night at one of New Kids On The Block‘s sold out Madison Square Garden shows, 50 Cent joined the boy band on stage. 50 Cent performed  “In Da Club” in front of the audience before going into “Lotto” with a little help from Rotimi, Lloyd Banks and Tony Yayo. 50 then brought Mark Whalberg on stage to the sounds of “Good Vibrations.” Marky Mark looked like he wasn’t having it and didn’t perform the song but rather just let it play out.
