Adele is expected to "pull a Beyonce" and surprise fans with a new album. Rumor has it that Adele's new album will be called 25 and will be released September 25.

"The plan is to release internationally on iTunes as a complete surprise without any previous promotion or build-up publicity campaign," the source said.

"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," the source added.

A 2014 tour is also expected once the album is released. Meanwhile, Phil Collins is coming out of retirement to work with Adele.

"I've just started to work with Adele. She contacted me to write together," he said.

"I wasn't actuality too aware [of her]. I live in a cave [but] she's achieved an incredible amount and I really love her voice and I love some of that stuff she's done. So, to me, it's always an eye-opener. Educational," he added.

It is still unknown whether the new music will be classified as an Adele release, a Collins release, or collaboration between the two talented musicians.

Collins announced his retirement in 2011, but allegedly had a change of heart last year while promoting the musical 'Tarzan' in Germany.

"I've decided I kind of missed that writing creative stuff, so I'm trying to get back into writing, and that's getting into a certain headspace and personal drive," he said about working on new material.

Collins has not released an album of his own since Testify, which was released in 2012. He also hasn't toured since the Genesis reunion in 2007.

No other details surfaced about his recording or touring plans, but collaboration with Adele appears to be the best way to emerge from his musical retirement.

The two musicians were described as "masters when it comes to personal writing about messy breakups" by Rolling Stone.
