The 23-year-old singer made his debut solo television appearance on Wednesday night (17Feb16) as he performed his upcoming second single It's You on The Tonight Show Starring Jimmy Fallon.

Earlier in the show, Jimmy delighted fans by showing off Zayn's new album cover. The incredibly cute cover features a throwback picture of Zayn as a child, smiling into the camera with his hands placed under his chin. This childhood picture is juxtaposed by the fact that toddler Zayn has the singer's current tattoos all over his hands.

Zayn stunned fans when he revealed he was leaving world-famous boyband One Direction last March (15). However, his solo career has already got off to an incredible start, when his debut single Pillowtalk went in at number one on the Billboard Hot 100 chart - beating One Direction's previous number two positioning in the process.

It seems It's You could follow the success of Pillowtalk, judging by the audience's reaction to the performance on The Tonight Show.

Sporting new pink highlighted tips in his hair, Zayn wore a black coat for some added drama and gripped the microphone as he crooned the track's lyrics.

Following the performance, #zaynonfallon quickly started trending worldwide.

Zayn had previously revealed that he had penned It's You following his split from his Little Mix fiancee Perrie Edwards.

"I just felt like I needed to put myself out there on that just because it was a form of therapy for me and it did help get me through some s**t," he said during an interview with Zane Lowe on Beats 1 radio.

Mind of Mine is due for release on 25 March (16), which also marks the one year anniversary of him quitting One Direction.
