Sharon Osbourne has accepted libel damages from The Sun newspaper over a 2007 story which alleged she was driving husband Ozzy "to destruction".
The 56-year-old former X Factor judge accepted an apology and a substantial, undisclosed sum of money.
Her solicitor told the court that the allegations were "entirely without foundation" and "extremely distressing, hurtful and damaging".
The star was not at London's High Court for the settlement.
Solicitor John Kelly said the article, published in October 2007, claimed that Mrs Osbourne was "driving her frail husband Ozzy Osbourne to destruction" and was working him "so hard she will kill him".
It alleged that she was forcing the Black Sabbath star to perform in a series of live shows in order to fund her exorbitant spending.
The article continued: "Sharon will keep Ozzy on the road until, like Tommy Cooper, he dies on stage".
Mr Kelly said the publication had caused damage to his client's personal and professional reputation and she had suffered considerable embarrassment and distress.
