Adam Levine's biggest fan had a panic attack upon meeting him, so the singer laid down on the floor to get a photo with him

(Kane Show)

Christopher Warner, a 10-year-old from Maryland with Down syndrome, is pretty serious about Maroon 5.

So serious he made this fan video (below), in which he rather adorably prints out all his favourite photos of the band.

It was picked up by Hot 99.5's Kane Show, which arranged for Christopher to go backstage at the band's show in Washington DC and meet them.

The boy was so overwhelmed by meeting his heroes however that he suffered a panic attack and had to lay down on the floor.

But Levine then simply laid beside him and suggested everyone else do the same, before taking photos on the floor and generally hanging out down there.

"[Christopher] has just been fascinated with Maroon 5 and especially Adam Levine," Avery Stanert, a special education teacher at the school, told The Today Show. "He loves to listen to their music during work breaks. He draws pictures of them. He just absolutely loves them."
