Adele's eagerly anticipated third album will reportedly be released mid-2014 after she is said to have starting recording sessions on Monday (April 22).
According to The Mirror, the Skyfall singer's decision to return to the studio has prompted Columbia Records execs to alter plans to release Susan Boyle's LP in the US.
It is thought that Adele's new record is being prioritised over SuBo's fifth studio LP - with both singer's sharing the label in America.
An industry source explained: "Both Adele and SuBo have done incredibly well and both are very important artists
"While SuBo is still a big-hitter and there are high hopes for her next album, Adele is the priority. Stateside, she has never been hotter.
"Some of those within Susan's camp are worried that this is not a good sign, but label bosses have been quick to reassure them that Susan still has an incredibly bright future."
The insider continued: "Adele is currently in a recording studio in London and it's in lockdown mode for the next few weeks. Four tracks are finished in terms of writing and she's now laying down preliminary vocals with backing music and singers.
"The rest of the record will be done in LA. The feel is very much Adele going back to her roots, with some modern jazz and a couple of classic old songs."
Both the Britain's Got Talent star and Adele's forthcoming albums were said to have been scheduled for US release within a few weeks of each other, with the source now suggesting it is likely they will released months apart.
