Mayor Rahm Emanuel and “Empire” guest star Rumer Willis took in the Jacob Banks set off-stage Saturday at Lollapalooza in Grant Park.

Emanuel wore jeans, a short-sleeved shirt and sunglasses as he bobbed his head to the British singer-songwriter’s performance before meeting Banks backstage. Emanuel was also spotted Thursday at the Ryan Adams aftershow at the Vic Theatre.
