Keeping up with reality star Lady Sitwell

FORGET Keeping Up With The Kardashians, will society be able to keep up with Martha Sitwell?

I hear the former ‘face of Royal Ascot’ has signed up for a docu-series about her fascinating life.

The ex-wife of film-producing baronet Sir George Sitwell confirms that work has begun. ‘We’ve done a couple of days filming,’ the daughter of late gastronome Justin de Blank tells me, declining to provide more details.

The socialite, 42, gave birth to a son when she was 17 and decided that the baby should be raised by her aunt.

She admits that Prince Harry’s soulbaring has, though, made her nervous about disclosing details of her private life: ‘The Harry memoir made me think, “Oh, God, do people need to know that?” I’m just incredibly honest at all times and happy to cover most things.’
