Ed Sheeran performs live at the Canadian Tire Centre on June 3, 2015 in Ottawa, Canada.

If you're casually singing some Ed Sheeran at your local mall, fair warning: Sheeran himself may join you for a rendition of "Thinking Out Loud."

Sheeran recently swung by an Edmonton, Canada, mall, where 13-year-old Sydney Bourbeau was performing at a fundraiser for Edmonton Humane Society. Midway through the performance, Sheeran rushed the stage (typically super rude, but we're guessing she didn't mind at all) to turn the song into a duet.

Bourbeau deserves major props for not outwardly freaking the heck out during the self-described "best moment in [her] life," instead calmly finishing out the tune before Sheeran raced off. While she didn't get to talk to him after the impromptu performance, she told the local paper that his team reached out and gave her tickets to an upcoming concert, so the two will be singing together again in the future (albeit this time with thousands of other people).
