Jason Derulo gives a surprise performance at a SoulCycle class

Jason Derulo surprised an unsuspecting class of SoulCyclers in Los Angeles this morning to kick off a week of pop-up events all across America leading up to “Good Morning America”’s first summer concert in New York City’s Central Park on Friday, May 19.

The SoulCycle regulars thought they were being filmed to showcase the hottest workout trends and had no idea Derulo was right outside the door, ready to bust in to give the class the surprise of a lifetime.

“I’m so ready. I’m so pumped right now,” the singer-songwriter said moments before performing his new single, “Swalla.”

The riders waved their workout towels over their heads as Derulo kept the energy up in the early-morning class.

“I hid in a pile of towels,” he joked of how he kept the surprise a secret. “I don’t think anybody knew what was going on.”

Derulo performs at the Billboard Music Awards Sunday night on ABC, and joins the “GMA” summer concert series on Sept. 1.
