Details of the Someone Like You singer's third album have so far remained pop's best-kept secret.
But I can exclusively reveal that the follow-up to second album 21 is already complete and will be released unexpectedly without prior warning - just like Beyonce's last record.
“Theoretically it could be released tomorrow if she wanted ”
I'm also told the album is likely to be called 25, keeping in sync with her previous albums 19 and 21 both named after her age while recording them. My source says: "The album is written, recorded and finished.
"Theoretically it could be released tomorrow if she wanted.
"The plan is to release internationally on iTunes as a complete surprise without any previous promotion or build-up publicity campaign.
"The shock tactics worked amazingly well for Beyoncé and the feeling is Adele's new album is so widely anticipated it doesn't need a long promotional build-up."
No release date has yet been decided but when it is only Adele an a handful of trusted people will be privy to it.
Though if I was placing a bet I'd go for October or November. Adele is then likely to play a few select concert dates to promote the album with a potential tour pencilled in for 2015.
The new music will be a welcome return for mum-of-one Adele who has been AWOL for the past year or two.
