Beyonce is 'one song away' from completing her new album.
Singer/songwriter Sia told MTV Australia that she had been trying to contribute to the project.
She told them: 'So I just said to all the producers, writers, everyone 'help me make this happen,' and then (producer) Diplo emailed me and said, 'where are you in the world right now? Would you be interested in flying to New York? I'm writing with Beyonce,' and I was like, 'Yesss!'
However, she was unable to fly out due to scheduling conflicts, but was still pitching songs to Beyonce. When asked if her submissions were for Beyonce's forthcoming album, Sia said: 'Well there's only one song left for this album, so I probably won't get on this album but hopefully the next one. That's my dream, that's my goal.'
As well as Diplo, Beyonce is said to be working with New York punk band Sleigh Bells on the album.
