Star sightings: Chance the Rapper, Michael Sam, Jillian Michaels

SEEN ON THE SCENE: Since unemployed gridiron star Michael Sam has some extra time on his hands, he’s apparently been around town hanging out with the cast of “Empire,” including Terrence Howard, Jussie Smollett and Gabourey Sidibe. But don’t jump to conclusions about the openly gay Sam and Smollett, despite Sam posting numerous Instagram shots of the two spending time together. As TMZ reported, it seems the two guys are just pals — at least at this point. … The super popular Chance the Rapper dropped by iO Theatre this week to catch the “3Peat” improv show.
