Holly Willoughby is facing a legal battle with her former agents worth millions, it's claimed.
The This Morning presenter, 40, is said to have hired lawyers to fight demands for commission from her former managers, YMU Group.
She has reportedly been told she faces a potential seven-figure payout should the firm, which also represents Phillip Schofield, Amanda Holden and Ant and Dec, be successful.
Their reported case focuses on sunset provisions, in which agents collect commission from a celebrity who has left them.
The payout would include a cut from Holly's contracts, should they continue, which include This Morning and Dancing On Ice.

A source told The Sun: "No one wanted this to go legal but Holly won't simply give away her hard-fought millions without a fight."
The sunset provisions clause means that YMU would get around 15% of new contracts Holly signs if she was with them when she originally started that gig.
If she signed a new deal with ITV worth £10million, say, they'd be entitled to around £1.5million of it.
This is despite her leaving YMU and now being managed by the firm she set up, Roxy.

The source added: "This is a sad finale to what was once a hugely successful partnership.
"But YMU seem unhappy she's set up on her own and feel entitled to maximise a sunset provision to claim commission on the renewal of contracts."
Holly set up Roxy in August to manage herself and employes only female staff.

According to The Sun, YMU had threatened her with legal action.
It's claimed both hoped to resolve the matter without it going to court.
Holly could be quizzed over her earnings should the case go to court.
The Mirror has contacted YMU Group and reps for Holly Willoughby for comment.
