Beyonce has almost wrapped-up work on her next studio album, meaning the record could be out as early as this summer.
Singer and songwriter Sia revealed she has been trying to collaborate with Knowles on the follow-up to 2008's I Am... Sasha Fierce, but Bey has nearly completed the record.
Revealing how she got involved in the project, Sia explained: "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!'"
When asked if her contributions will make the record, Sia told MTV Australia: "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."
Beyonce previously promised the album will be diverse. She also revealed that the record will feature live instruments.
