- Lady Mary was raised on estate in Gloucestershire featured in Harry Potter films
- Her parents are some of the most colourful members of the British aristocracy
- Model Lady Mary, 30, has carved out a niche as the ultimate Sloane Raver
What a dazzling, gilded life she has. Her social diary is an enviable round of parties, festivals and fashion shows, with celebrity friends who include Rita Ora, Alexa Chung, the Delevingnes and Georgia May Jagger.
But it's not all sweetness and light for Lady Mary. For she has, it seems, made a couple of enemies during her rise to fame and social ubiquity
Model Kate Moss is no fan, reportedly pushing her into a swimming pool during an altercation at a party in 2013.
La Moss — who is a creaking 13 years her senior — felt that up-and-coming party girl Lady Mary had shown a closer interest than was properly polite in her then husband, Jamie Hince.
In 2015, as the Moss-Hince union fell apart, Lady Mary was on hand to escort Hince around Glastonbury, and he was even said to be sleeping on the sofa of her West London flat for a time.
The footballer's publicist Simon Oliveira yesterday denied the report, describing it as 'completely untrue and absolute nonsense'.
Another source close to the couple said that there wasn't any animosity with Victoria because Mrs Beckham was 'unaware that there was a wider friendship' between her husband and Lady Mary.
So what's the truth? Victoria is widely reported to mistrust Becks' best pal Gardner, who is friends with a party-hard crowd whom she regards as 'dreggy'.
A source said: 'David loves the wild crowd whom he knows through Dave Gardner and Guy Ritchie. He's really into music, so it's no surprise that he would get on well with Lady Mary.
'At the moment Victoria is horribly busy with her fashion and launching her make-up range. David seems to be rattling around town having a bit of a mid-life crisis.'
So who is the posher-than-Posh beauty who has a habit of turning every head?
Lady Mary Chateris is the daughter of Jamie Neidpath, the Eton-educated son of the 12th Earl of Wemyss. He was a page of honour to the Queen Mother, and he now runs the Alro Group, a property fund management company.
He had a distinguished academic career, taking a BA at Oxford in 1969, followed by an MA and then a DPhil. At this time he was said to have taught former U.S. President Bill Clinton, who was a Rhodes scholar.
Jamie married the Hon Catherine Guinness in 1983, and had son Francis, the heir, and daughter Lady Mary.
