Having apparently run out of human beings to collaborate with, Madonna's next single might have a helping hand from a very familiar voice to iPhone users.

Speculation is rampant today that Madonna is set to put out a new single in the very near future and that it might feature the voice of Apple's iPhone virtual assistant Siri on the track.

The song - apparently called either 'Unapologetic Bitch' or 'Bitch, I'm Madonna' - has been the source of online speculation since it was noticed that saying "Unapologetic Bitch" to Siri would redirect you to Madonna's Wikipedia page, which itself makes no mention of the search terms adding further fuel to the fire that some sort of Apple/Madonna partnership is underway.

Asking Siri if she is involved in the Madonna track leads to a response saying: "No comment."

Madonna's 13th studio album is understood to be out later this year and will also feature contributions by the London Community Gospel Choir, Diplo, Avicii while Diplo has admitted to producing seven tracks from the forthcoming collection.

Madonna's Instagram account continues to release hints and teasers about the new album too, usually along with a hashtag containing some variant of the word 'Bitch' - hence the speculation above.
