But at one point of his secret gig the singer attempted a stage dive and the crowd was not able to support Styles and the 23-year-old singer crashed on the floor.
Harry Styles is the former One Direction singer, and his first solo album is finally here.
As well as telling the stories behind his new music, Styles also took questions from fans.
Harry Styles begged for his publicist to intervene when asked if his song Two Ghosts was written about his ex-girlfriend, Taylor Swift. "I really loved being the new guy, to be honest". He said: "I happened to be driving along and I heard Harry's single". They also echo certain lines from Swift's 1989 song "Style", which fans have long theorized was about Styles: "You got that James Dean daydream look in your eye / And I got that red lip, classic thing that you like".
Grimshaw chose to do Styles "a favour" by addressing the rumours that his track Two Ghosts is about Swift, whom he dated briefly in 2012.
"The beginning of Sweet Creature sounds like Black Bird, and Harry Styles is trying to destroy us all", one person wrote on Twitter, while another added, "Sweet creature by harry styles is like a chord off from Blackbird by the Beatles".
"When we started, I didn't know what it was going to sound like, or what I wanted it to sound like".
I think it would be weird to be making a record during the past 18 months and not comment on how [the political landscape] was making me or the people I know feel, which is not good. "I'm doing you a favor here", the host said. "But now it's one of my favourite songs on the album".
The first track, "Meet Me in the Hallway", and one of the album's strongest, starts off a little odd.
However, it's kind of the One Direction alum's fault as he clearly penned a track about his superstar ex for his new album.
