Simon Cowell is reportedly in secret talks to join the BBC.
The X Factor judge, who has worked with ITV for the past 11 years, is said to feel "betrayed" by the "unsupportive" broadcaster.
His relationship with the channel has apparently hit an all-time low, just weeks after unofficial biography Sweet Revenge: The Intimate Life of Simon Cowell claimed he was upset and annoyed with ITV over its lack of support for Britain's Got Talent and The X Factor.
Cowell's Talent has been in a well-publicised ratings battle with BBC rival The Voice UK, forcing the ITV1 show to change its timeslot.
The Syco boss is reported to have personally wooed BBC One controller Danny Cohen with a new idea for a drama.
"Simon rang Danny Cohen to congratulate him on how well The Voice was doing. He then said he had a great idea for a brilliant drama and outlined it," a source told
The Mirror.
"He's gone off to do a proposal and it will be treated like any other idea from an independent production company. If it's brilliant then great. We'll see a treatment then get it developed in the normal way."
However, another source claimed that Cohen has been "dismayed" to hear that Cowell has been bragging to friends about his "new BBC drama" before it has even been commissioned.
"We're a long way off any commission. We're happy to talk but there's a feeling we could be being used in Cowell's ongoing war with ITV," the insider said.
"Cowell wants the BBC to know he could be working with us - this is his way of flexing his pecs and showing them he has options. Danny doesn't want to be played off by Cowell."
Cowell's 'right-hand woman' Shu Green was poached by ITV last week after ten years at Syco. He allegedly viewed the move as a "slap in the face" and rang the ITV Studios boss Denise O'Donoghue to demand an explanation.
He is also said to be unhappy that ITV overruled him on the decision to rehire Gary Barlow for The X Factor, who he wanted to sack for being "too scripted" and "a bit stiff".
Cowell was a consultant on 2008 drama Rock Rivals, which starred Michelle Collins, but later pulled out.
