Adele has hinted in a cryptic message on her Twitter account that her new album could be imminent and will possibly entitled “25”.

She tweeted: “Bye bye 25... See you again later in the year x”, causing fans to speculate that her new album could be titled “25” following “19” and “21”.

Adele has been working with OneRepublic front man Ryan Tedder on material for the new album and he has said that she would release music “on her own timetable”.

He continued: "I haven't heard everything she's done, but I've heard everything we've done and I'm as proud of it, or prouder of anything we did on the first album, and she is sounding even better than ever."

The new album will follow 2011’s “21” which has so far sold over 25 million copies around the world.
