According to The YBF, Kevin Hart appeared on “Dancing With The Stars” as a guest judge last night. It was Movie Night on “DWTS” and the contestants got down to some tunes from their favorite movies. Kevin sat in for judge Len Goodman. And before he got on his judging duties, the Wedding Ringer star, alongside his co-star Josh Gad, cut a rug to “Born To Hand Jive”, which was made famous from the musical romantic comedy film Grease. Sidebar: Why did Kevin really dance great. Lol!
