It's been a decade since Zayn Malik left One Direction and on Tuesday night (March 25) during the singer's show in Mexico City he did something he hasn't done since then: he performed one of the group's most beloved hits during a solo show.

I remember it like it was… a decade ago. Zayn Malik announced his departure from the biggest boyband in the world. I didn’t publicly care too much about One Direction in 2015, mostly because I wanted people at my college town’s house shows to think I was cool.

Zayn Malik stunned One Direction fans in 2015 when he announced his sudden departure from the band – the first domino in the band's eventual breakup a year later. Now, almost a decade later, he stunned fans by performing a One Direction song at one of his concerts.
