Thought a Claire's clearance or Wet Seal sample sale meant the mall gods were looking down on you favorably? Well, 13-year-old Sydney Bourbeau's recent trip to the West Edmonton Mall in Alberta, Canada amounted to some good fortune that's typically unheard of around the Best Buy and Auntie Anne's Pretzels.

On Sunday, the Canadian teen was singing Ed Sheeran's "Thinking Out Loud" as part of her music school's fundraiser. Sheeran, who happened to be browsing in the mall's HMV (huh? what? we know), suddenly rushed the stage for a spontaneous duet and left the teen nearly speechless. We've got to give Sydney credit for finishing her set and, you know, not passing out.

"I was like, 'Should I stop?' I didn’t want to stop, but I wanted to talk to him,” Bourbeau told the Edmonton Journal, and added that she originally thought Sheeran was a technician who'd joined her on stage to fix her microphone. “This is, like, the best thing that’s ever happened to me.”

The Journal reported that Sheeran's manager followed up on the performance by offering Bourbeau two tickets to Sheeran's show at nearby Rexall Place, and that the superfan decided to take her mom.

"Crying this was the best moment in my life," Bourbeau tweeted after all had been said and done and she finally caught a clip of the small-scale show.

Ever heard of anything like Sheeran's show-stopping drop-in, and can you believe Bourbeau's lucky timing? Check out the clip, and remember: No gig is beneath you!
