At one point in time, One Direction was the biggest boy band in the world -- but all that slowly came to a halt in early 2015 when Zayn Malik announced his departure. Seemingly following Zayn’s footsteps, the rest of the band members -- Harry Styles, Louis Tomlinson, Niall Horan and Liam Payne --started to soon after work on their own solo careers.

Harry, Louis, Niall and Liam announced in December 2015 that One Direction would be going on hiatus. While no music would be made in a year or two, the boys promised to return refreshed and ready to pick up where they left off. Technically not breaking that promise, the boys have started to make their own music and have had relative success in being separate acts.

Harry Styles has been silent on the music front of his career, with rumours only indicating that a multi-million dollar deal has been signed with Columbia Records. What is for certain, however, is that the 22-year-old has been busy filming for “Dunkirk,” a World War II drama from Christopher Nolan.

Earlier reports indicated that Louis Tomlinson would be taking a break from the music scene, at least as a front runner. His previous mentor, Simon Cowell, confirmed with Mirror UK that the girl group being backed by the 23-year-old is one of the best that he has heard.

Louis has apparently taken his duties as a father more seriously as well. He is reportedly filing for joint custody of his son, Freddie Reign, whom he had with ex-girlfriend Briana Jungwirth.

Niall Horan, on the other hand, is experiencing some very early success in his solo career as a musician. His first single titled “This Town,” which he released over social media, has been well received. It even hit no. 1 on the Billboard + Twitter Top Tracks.

Liam Payne has meanwhile signed with Republic Records, a prominent music label in North America, which represents other stars like Ariana Grande, The Weeknd, Nicki Minaj and Drake. Republic Records stated that Liam would be releasing new music “soon.”
