The reality TV mogul is also claimed by The Sun to be fighting to save long-serving show judge Louis Walsh - amid claims that ITV bosses want to see the back of the Irish pop manager.
A source on the show told the paper that Tulisa, 24, had not been officially told of her exit - but said her lack of pop success was also a factor.
"Quite apart from her performance on last year's show, you can't have a singer whose album only reached No 35 in the charts sitting in judgment on other singers.
"Tulisa has been on the panel for two years. She had a good run, but all good things come to an end."
And the same source claims that SiCo is determined to keep his pal Louis for a 10th year on the UK version of the show.
"He will fight tooth and nail to keep him on the show," the source said.
"It hasn't reached the shouting stage yet — but if it does, Simon is prepared for the fight."
We told you yesterday how Robbie Williams is reportedly the top target for the show.
