Earlier this month, Adam Levine and Maroon 5 attended and performed at the 55th Annual Grammy Awards on Feb. 10. Their performance with Alicia Keys went off without a hitch, but the real problem occurred when Adam and his mom (who he took as a date) tried to take their seats.

A prankster crashed the Grammys and sat in Adam’s chair! The tattooed rocker recently spoke with 92.3NOW about the incident, and he had a clear message for his seat stealer.

“To that prankster that did that: F you, man! Seriously, I was with my mother at the Grammys and you had to get your rocks off by coming to the Grammys and refusing to get out of the seat?” Adam said.

Adam first learned something was wrong when they were escorted to their seats and someone was already in them. The prankster refused to move and Taylor Swift’s opening performance had started.

“We’re standing [in the aisles] like jerks,” he said. “I didn’t want to deal with that, so I went and sat down on Blake’s lap. Shelton had front-row seats so I just sat in his lap. And then I kinda just sat on the floor cross-legged for the first 15-20 minutes of the Grammys.”

A seat on Blake Shelton’s lap? That doesn’t sound like the worst thing in the world. But Adam was still pretty peeved.

“To be inconvenienced by that kinda bulls was annoying,” he admitted. “Not for me, I don’t care, but that my poor mother. She was my date. Really screwed that up, buddy. Might want to rethink your pranking.”
