Can you imagine going to see Shawn Mendes in concert, and having freaking ED SHEERAN crash the party.
Last night, fans were treated to this exact scenario when they attended Shawn's New York concert at Barclay's Centre.
The two performed Shawn's hit song "Mercy" together.
Shawn is currently on the North America leg of his Illuminate World Tour, and he will be headed to Australia at the end of the year!
Can he bring Ed along with him too?!
