The 'Little Things' group went on hiatus at the beginning of the year, and despite speculation they have gone their separate ways permanently, the 23-year-old singer - who is expecting his first child with girlfriend Cheryl - insists they will reform in the future.

Asked if the band will get back together in a Twitter Q&A with fans, Liam replied: "I'm [100 per cent] certain that we will."

But before One Direction - which also includes Niall Horan, Louis Tomlinson and Harry Styles - can get back together, Liam will be following in the footsteps of some of his bandmates and releasing solo material.

Asked when his album will be out, he told one fan: "I'm making it right now (sic)"

And he told another: "listen yeahhhhhh albums coming soon!!!!!! Hol tight for da rewind (sic)"

But his work is temporarily on hold as he's not feeling well.

He admitted: "I am at home and am sick so I can't record at the moment."

Liam's reassurance for fans comes shortly after bandmate Niall - who recently released debut solo single 'This Town' said it would be "ridiculous" if One Direction didn't get back together.

He said: "At the moment we are all doing our own thing. Everyone is just enjoying just how chilled it is.

"Harry wanted do is his movie and everyone is just chilling. I don't think anyone needs to worry about us we are fine.

"We will be back. We would be silly not to... ridiculous."

It isn't the first time the 'What Makes You Beautiful' singer has hinted at the return of One Direction either, as he previously stated there would be "plenty more" material from the boy band.

He said: "There's going to be plenty more One Direction shows, that's a guarantee so it's not a case of one more show. There's definitely more than one more 1D show coming up, that's a fact."
