Instagram video shows the shock on the artist's face when he gets the message of Eminem's arrival in his ear monitors.

The hometown rapper ignited a roar when he hit the Ford Field stage to perform "Lose Yourself" with Jelly Roll as Post Malone's stadium tour hit town.

Jelly Roll's performance at Ford Field on Sunday night was certainly one to remember. The country star performed the opening set at Post Malone's Big Ass Stadium Tour, and he brought out one very important person who has connections to the Lions.
