Today is a day for firsts! Or rather yesterday…

Calvin Harris made his US television debut on Jimmy Fallon last night with Will Smith, and Zedd & Selena Gomez finally perform their song “I Want You To Know” together at Z-100 Jingle Ball in New York.

Selena has performed the song solo before, but this marks the first occasion that the two have performed the platinum selling track together on stage.

It was suspected that the two would perform together at L.A.’s KIIS-FM Jingle Ball Dec. 4, but sadly it didn’t happen. We’re happy to see it finally did!

Reunion with my favorite lil Mexican taco Selena Gomez to perform “I Want You To Know” at Madison Square Garden last night.
