Cody Simpson on Justin Bieber collaboration: 'We wrote 12 songs in seven days'

Cody Simpson has revealed the prolific nature of his Justin Bieber collaboration.

The two singers have recently been in the recording studio together and the project is expected to see the light of day before the end of the year.

Speaking to Tribute, Australian Simpson said that the duo have penned over ten songs for their acoustic-led project.

He said: "We went in and ended up being in the studio till six in the morning, came out with a song, went in the next night and then ended up writing, like, 12 songs in seven days, working all night.

"We're both very different people and we're both inspired in very different ways but I was able to come in and play some guitars and we were able to write some beautiful songs together, pretty acoustic-sounding, so you'll hear some music this year."

Simpson meanwhile recently said that he is "just taking it back to my roots for this one. It’s pretty raw, but it’s pretty cool stuff. Beautiful music.”
