Sir Paul McCartney'S ex-wife Heather Mills is facing a court battle with her former nanny - following allegations she was made to go far beyond her duties as their daughter's caretaker.
Sara Trumble resigned from her post as nanny to Beatrice - Mills' daughter with MCCartney - in September (08).
According to British tabloid the Sunday Mirror, Trumble claims Mills made her work as late as midnight, blow dry the ex-model's hair at 7:30am and even give her naked spray tans.
The pair have 28 days to settle their differences or risk thrashing out the dispute in court since Trumble lodged a constructive dismissal claim with an employment tribunal last week (begs15Dec08).
A source tells the publication, "Sara and Heather started out as friends but it all went wrong after Heather's divorce.
"Heather is concerned what Sara will say - she was in the heart of the family during the last days of her marriage to Sir Paul right up until after the divorce was finalised."
Mills is worth an estimated $35 million (GBP24 million) following her lengthy divorce from ex-Beatle MCCartney earlier this year (08).
