Calling Jessica Biel your college roommate has certain perks.

On Saturday, Dana Panzer, who was Biel's roomie at Tufts University, tied the knot with her girlfriend Amy Wicker in Norwalk, Connecticut. The newlyweds received a priceless gift at the reception: a surprise performance from Biel's husband Justin Timberlake, who was also in attendance.

J.T. sat down at the keyboard to perform his hit song "Señorita." You can watch a snippet of it courtesy of model/TV personality Kim Stolz, who shared a video on her Instagram account.

Nothing gets people on the dance floor like an impromptu Justin Timberlake concert!
