Party treats and a touch of Zen...

THE QUEEN’S beloved cousin Princess Alexandra threw a sumptuous feast for her granddaughter’s 31st this week.

Zenouska Mowatt, who works for the Royal Warrant-holding luxury goods company Halcyon Days, celebrated at home with friends.

But not before her granny had invited her to the Thatched House Lodge in Richmond Park, where she was treated to sandwiches, scones, choux pastry swans, chocolate cake and champagne.

Zenouska’s mother, Marina, was dubbed the ‘royal rebel’ in 1989 after becoming pregnant outside marriage.

It led to a rift between her and her parents after she publicly accused them of ordering her to marry her boyfriend, photographer Paul Mowatt, or have an abortion.

She walked up the aisle dressed in black and Zenouska was born four months later.
