The X Factor judge, who is hosting the ceremony with Ozzy in February, is still in talks to organise the possible duet.
"Sharon is a very determined woman and wants it to be the best Brits ever," a source told The Sun. "She's been in touch with lots of the legendary music business names she knows personally.
"It was her idea for a duet between Ozzy and Sir Paul. If it happens, it will be unmissable."
