'Empire' Stars Slay at The Grove (VIDEO)

It was like one-stop shopping Friday night at The Grove ... you could get a soft pretzel, check out the creepy dolls at American Girl, and watch a concert courtesy of the fine folks at "Empire."

Jussie Smollett, aka Jamal, Bryshere Gray, aka Hakeem, and others performed for the cheering crowd.

Before the concert, the audience got to see an episode under the stars, and then got to ask the cast members questions.
