Also marking Styles’ birthday was his One Direction co-star Niall Horan, who jokingly referred to him by a nickname.
Horan tweeted: “@Harry_Styles happy birthday Harold. Have a great day pal.”
One Direction hair and make-up artist Lou Teasdale shared a snap of herself with Styles on Instagram and wrote: “Happy birthday boss man best friend xxx.”
Fans of the boyband star made sure his birthday became a trending topic on Twitter as they flooded the site with posts wishing him a good day.
Styles rose to fame at the age of 16 on The X Factor when he auditioned as a solo singer before being put into the newly-created band One Direction, along with Horan, Zayn Malik, Liam Payne and Louis Tomlinson.
The band is currently on hiatus and Styles has since gone on to enjoy success as a solo artist, with his debut solo single Sign Of The Times topping the charts last year.
He has also carved out a career as an actor, making his big screen debut in Christopher Nolan’s war film Dunkirk.
