Adele is currently working on her third studio album, which may not arrive until the end of the year.

A source close to the British artist's team told Music Business Worldwide that "logically, there is now almost no chance," of the long-awaited record being ready for release before "the second half of 2015."

Another source suggested Adele may not even drop her latest project this year: "The album will be released when it's ready – [we] hope that will be at some stage in 2015. That's all I can tell you right now."

The source added all parties working with the "Someone Like You" hitmaker – including Columbia Records, U.K.'s XL/Beggars, as well as management company September – are actually supportive of her taking her time with the upcoming LP.

Similarly, Adele's producer Paul Epworth told Billboard recently, "I've got nothing. There are no clues. That will come when it's ready."

Meanwhile, the "Rumor Has It" singer's forthcoming collaboration is going to be a very "happy" one, according to Daily Star.

"Adele is back in the U.S. to finalize her new album and she's making some 11th hour alterations. She wants to try something different with Pharrell," a source said.

Skateboard P would love to team up with Adele, as he praised her 2010 hit "Rolling in the Deep."

"I always thought it was special, man, that soulful, soulful voice," he said.

The "Chasing Pavements" singer's recording sessions in Los Angeles began in 2012. Adele reportedly arrived back in Los Angeles recently because she wished to let Eminem's go-to producer listen to her music.

"Adele wanted to go back to Malibu so Rick Rubin could give her his opinion," the source said.

In addition, Adele took to her social media account back in May to hint at the title of the follow-up to "21," when she turned 26.
