Five Seconds Of Summer have already dropped three singles from their upcoming fourth studio album in the past few months.

And on Monday, 5SOS singer Luke Hemmings confirmed the band's highly-anticipated album is now complete.

In an interview on Nova's Smallzy's Surgery, the 23-year-old said it was done and would likely be released in 2020.

'We've written all we could write': Five Seconds Of Summer singer Luke Hemmings says the band's highly anticipated fourth album is complete. He said: 'It is done [the album], I would say… hopefully it's done!'

'We've written all we could write at this point, but yeah it should be done and it'll come out probably next year, but we'll have a bunch of music out before then.'

He added that the band will release more tracks in the lead up to the release.

'I can tell you that we're going to put out a few songs, like more than usual, probably, I want to say four at least, before the album actually drops.'

Host Smallzy asked the lead singer to clarify for the fans what stage the album was in and if the band needed to write and produce more music.

Luke explained: 'It can happen and it kind of depends on like, for instance we put out Easier and then we put out Teeth, and if people were like "Oh we don't like this", then we'd have to re-think it.'

'But luckily people are liking the songs we're putting out and the rest of the album matches that, so hopefully we'll be all good.

He continued: 'There's about 12 songs kind of signed off at the moment which is enough, but you never know we might write more songs for it and have a longer album.'

The 5S0S frontman also said he and the gang are looking forward to being back home in Sydney for summer.

'Yeah we’ll be home for Christmas, we always try to be home for Christmas and New Year’s in Sydney for sure!'

Five Seconds of Summer started in 2011 and first came to fame through posting cover songs on YouTube.

They skyrocketed after members of One Direction, Louis Tomlinson and Niall Horan, each shared the Australian band's music on their social media accounts.
