The late Lady Bathurst (pictured) cut her stepson completely out of her will
When the earl married an American heiress in ITV's hit drama Downton Abbey, it helped secure the future of his family's stately home.
In the real-life case of Earl Bathurst, an Anglo-American union has left his estate bitterly divided.
For I can reveal that Lord Bathurst has not been left a penny by his late American stepmother, Gloria, Dowager Countess Bathurst.
Instead, she bequeathed almost her entire fortune of more than £33 million to a pair of interior decorators.
'The Countess's will has left the whole estate in deep shock,' a source tells me.
'While it was known that Gloria had her differences with her stepson, no one thought she would cut him out of her legacy entirely.'
Gloria lived at Cirencester Park, which has a 15,000-acre Gloucestershire estate and a polo club where Princes William and Harry have often played, until her husband's death in 2011.
Newly released probate documents disclose that the Countess, who died last Christmas aged 90, decreed in her will that the vast bulk of her of £33.2million estate should be shared equally between Grant White, an interior designer based in Fulham, and New Yorker Geoffrey Bradfield.

The estate is understood to include an entire village.
