Watch Shawn Mendes And John Mayer Make Sweet, Sweet Music Together

Sorry, Camila Cabello, but it looks like John Mayer might be Shawn Mendes’ new duet partner of choice.

Mendes joined Mayer onstage Monday night at Toronto’s Air Canada Centre for a surprise collaboration. The pair blended Mendes’ hit “Mercy” with Mayer’s classic “In Your Atmosphere,” creating the magical mashup we never knew we needed. Watch their full performance below.

It was a banner night for Mendes, who is a longtime fan of Mayer’s. The “Stitches” singer has called Mayer’s songwriting his “favorite lyrics of all time.” It seems as though Mayer is equally in awe of his 18-year-old counterpart after their collaboration. Mayer shared a photo of the duo onstage, calling Mendes “dynamite” and dubbing their duet “over the top good.”

After listening to their harmonies, we can’t say we disagree.

Mendes, for his part, seemed humbled by the chance to perform with his idol. The teen sensation tweeted his appreciation for Mayer and his fans.

More collabs from these two, please!
