Harry Styles is to make his eagerly-awaited music comeback next month.

The 'Watermelon Sugar' hitmaker recently filmed a music video for his new single on a giant bed outside Buckingham Palace in London, and now it's been claimed fans will get to hear the One Direction star's first new solo music since his 2019 LP 'Fine Line' in April.

A source told The Sun newspaper's Bizarre column: “Harry’s lead single is coming this month and his fans are in for a real treat.

“He has worked so hard on this track and it’s going straight to No1.

“The video is going to be just as good as the song. While fans might think they have seen it all, Harry actually saved the best bit for behind closed doors.

“The fashion and the features in the secret shoot for the video are incredible.

"Harry really pushes the boat out. He is absolutely thrilled with what they have created and can’t wait for people to hear the song and see the video.”

The 28-year-old singer - who is reportedly set to release his third solo album later this year - was seen lounging on the large mobile bed, wearing polka dot pyjamas and a pink and green scarf, while surrounded by women in similar attire for the promo.

A source told the newspaper last month: "There was loads of security around him trying to move people away and the road was closed.

"They shut down the Mall for him to film on a big bed surrounded by women dressed as hippies.

"Harry was wearing retro clothes and it was reminiscent of John Lennon's famous bed moment with Yoko Ono.

"He was in the moment and not all distracted by people watching. It was freezing cold so at least he had bed covers to warm him up."

Since the release of his second studio album - the follow-up to his 2017 self-titled debut album - Harry has gone on to film the movies 'Don't Worry Darling' and 'My Policeman', along with a post-credits scene for Marvel's 'Eternals'.

Harry has reportedly been working on the new album since early 2020, with a source previously saying: "Harry started working on the album in early 2020 and had a few writing sessions under his belt before the pandemic really took hold.

“As a result plans were put on ice but most of the record ended up being recorded in the UK.

“Right now exact details are top secret but the tracklisting should be decided soon.

“Harry is really excited about the album.”

After he completed his 42-date 'Love on Tour' shows in the US last year, he hinted to fans that he would be back "very soon".

He tweeted: "Thank you for 42 special nights. It’s been a privilege to play for you the last few months. To the band, the crew, and everyone working on this tour, I thank you from the bottom of my heart. The energy you brought to this one has left me feeling completely overwhelmed with joy.

"To the fans, and everyone who came to see these shows, I thank you. You made them everything they were, and I’ve never felt so genuinely supported. I can’t say it enough, you’re unbelievable.

"This tour felt like the celebration of coming back together. I won’t ever forget it. Thank you all so much for the love, I’ll see you very soon. Treat people with kindness. Goodbye for now. I love you all. H."
