She was previously dubbed 'the blunder-prone Sloane' who is most well-known for her hand in raising the future King of England.
Alexandra Pettifer, better known as Tiggy Legge-Bourke, won a High Court ruling over allegations fabricated by the BBC that she had had an affair with Prince Charles and became pregnant while nanny to Princes William and Harry.
The broadcaster made a public apology, and was ordered to pay out over the unfounded claims made to obtain Martin Bashir's infamous 1995 interview with Princess Diana.
But who is the aristocrat that the princes reportedly referred to as their 'big sister'? Historical reports show the former royal assistant and nanny is no stranger to controversy, having frequently gone against royal protocol.
Strongly disliked by Diana, Ms Pettifer once referred to the royal princes as "my babies", breaching stiff rules.
The Royal household's current nanny to Princes George and Louie, as well as Princess Charlotte, was allegedly not allowed to refer to the children as 'kids', as it was deemed disrespectful.
The nanny also hit headlines in January 1998 after taking the young princes on a hunt, and passed out glasses of sloe gin as they chased animals.
The same year, St James' Palace launched an inquiry after it was revealed she had taken the young princes to abseil the 50-metre dam wall of Grwyne Fawr Reservoir in Wales.
But perhaps one of the biggest eyebrow raisers in Ms Pettifer's career was the gaffe when the then-34-year-old declined to invite Camilla Parker-Bowles to her wedding.
She married former Coldstream Guards officer and childhood sweetheart Charles Pettifer in October 1999, in a bash speckled with aristocrat names - except, of course, the later-to-be Duchess of Cornwall.
Already inviting former employer Charles and the young princes, the exclusion of Camilla was dubbed a huge gaffe at the time - and was reportedly after the the Duchess referred to Ms Pettifer as "the hired help".
While both William and Harry attended the day, Charles declined the invite claiming he had a prior engagement.
Meanwhile, following the recent BBC judgement, BBC Director General Tim Davie said the fabricated allegations of a dalliance with Prince Charles remained "a matter of deep regret".
He said: "The BBC has agreed to pay substantial damages to Mrs Pettifer and I would like to take this opportunity to apologise publicly to her, to the Prince of Wales, and to the Dukes of Cambridge and Sussex, for the way in which Princess Diana was deceived and the subsequent impact on all their lives."
