Watch Ed Sheeran Surprise Young Fan Singing His Song at the Mall [VIDEO]

Imagine singing one of your favorite singer's songs at the mall for a school fundraiser, when suddenly that star joins you onstage to make it a duet! That's what happened to Sydney Bourbeau of Edmonton Ontario. British pop star Ed Sheeran walked up during the 13-year old's performance of 'Thinking Out Loud' and sang right along with her.

Bourbeau tells the Edmonton Journal she couldn't believe what was happening to her.

“I was like, should I stop? I didn’t want to stop, but I wanted to talk to him,” she said. “This is, like, the best thing that’s ever happened to me.”
