The Voice coach has hit the headlines many times for her often revealing outfits, flashing her nipples on a night out with her acts last week.
And The Sun reports that the see-through top was the 'last straw', with Rita's dress sense having caused hundreds of complaints to both the BBC and Ofcom over the past few months.
A show insider told the newspaper today: “Bosses didn’t get involved when viewers complained about the revealing suit she wore on The One Show in January.
“But the T-shirt was felt to be close to the mark — and her see-through top took her right over it.”
However, a pal added to the tabloid: “She isn’t going to start dressing like a nun. That’s not her style.”
TV watchdog Ofcom said earlier this year it would not be investigating Rita's appearance on The One Show despite almost 400 complaints over a risque jacket with a plunging neckline.
Rita's look was again the talk of Twitter at the weekend but for very different reasons, with her furry shoes seeing plenty of jokes at the singer's expense.
The newbie coach ended up being been left with no acts in team after the latest live show with both Karis Thomas and Joe Woolford were eliminated at the weekend.
It means that this weekend's final can see Rita take a backseat as Ricky Wilson, Sir Tom Jones and Will.i.am battle it out with their singers in the grand finale.
