It's been quite the dramatic year for One Direction.

In March, Zayn Malik quit the group -- and just a few months later dumped his fiancee, Little Mix singer Perrie Edwards, too.

This spring, Louis Tomlinson also split with his girlfriend of four years, Eleanor Calder -- and a few months later confirmed that he's expecting a child with another woman he's no longer dating.

Then Niall Horan confirmed the band planned to take an extended hiatus in 2016.

Now 1D star Liam Payne and his girlfriend of two years, former schoolmate Sophia Smith, have ended their romance, reports The Daily Mail Online.

"Liam is incredibly sad, but is going to keep busy. He really hopes that everybody will respect both his and Sophia's privacy and stop speculating," an insider told The Daily Mail.

On Oct. 24, Liam fueled the breakup speculation when he tweeted, "I love how music is always there for you when you need it most x."
