Harry Styles called in to celebrate the release of his new single 'Sign Of The Times.'  

"Through the whole album, I wanted it to be really honest. I didn't want to kind of hide and I just kind of wanted to write what I wanted to listen to," Styles, 23, told us about the song. 

No official release date for his debut solo album has yet been announced. 

Photos and video footage leaked of Harry filming the video for 'Sign of the Times' a few days before the song's release. Fans were excited to see the One Direction member hanging from a helicopter

"To be honest I've never wanted to do that. It was crazy. It was amazing," Harry told us about the helicopter stunt. "I think the video is going to look good... hopefully."

Harry will appear alongside Jimmy Fallon as the musical guest on the April 15th episode of Saturday Night Live to kick-off the sketch show's 'live coast-to-coast' run for the end of the 2016-2017 season. 

You can also catch Mr. Styles this summer in his feature film debut for Christopher Nolan's upcoming World War II movie, Dunkirk
