Shawn Mendes rocked London’s Wembley Stadium when he closed out Capital’s Summertime Ball on Saturday, headlining a roster of acts that included such artists as Camila Cabello, Charlie Puth and Rita Ora.

During his performance, the 19-year-old Canadian singer had a few surprises up his sleeve, such as delivering a cover version of Frank Ocean’s “Thinkin Bout You” that segued into Mendes’ own “Treat You Better”; you can see that performance in the video above.
