R. Kelly hijacked a random dude’s cell phone this weekend in New York… then recorded a XMAS music video for the guy. LOL. On Friday night at Papa Juan Cigar Room in Harlem, R. Kelly showed up with his entourage. One of the guys began recording Kelly with his camera phone. Then R. Kelly jacked the guy’s cell … and recorded his rendition of “Chestnuts Roasting.” Hilarious. See below.
