SUMMER STARTS HERE! THE MARCHIONESS OF BATH - OUR SOCIAL EDITOR AT LARGE BRINGS US LAUGHS AND LOOKS FROM THE HOTTEST PARTIES IN TOWN

The London season sweeps you up in a whirlwind of exciting engagements, but there are three in particular that I always try to support: the Roya l Academy Summer Exhibition, and the V&A and the Serpentine Gallery summer parties.

Glamming up for the Serpentine at my mother Suzanna’s house with my friend, tennis legend Venus Williams – who was co-hosting the event – was like a pre-party of its own.

My dress for the evening was a strapless red gown from Vivienne Westwood, while Venus wore a custom white halter gown, brought to her by creative director of fashion label 16Arlington, Marco Capaldo – who had no idea he was coming to my house until I opened the door.

WHEELY FUN

Prepped and ready to go, we bundled into the back seat of my car – normally only big enough for my young sons John and Henry – which was like trying to solve a Rubik’s Cube.

When we reached Hyde Park, everyone was in fits of giggles as we carefully disembarked in the right order so as not to ruin Venus’s pristine dress.

A-listers and fashionistas turned out in force for the occasion, and we spent the evening rubbing shoulders in the elegant pavilion with society and style luminaries such as fashion designer, singer and socialite Daphne Guinness, It-girl Lady Lola Bute, actress Minnie Driver and model Jourdan Dunn.

After meeting the Serpentine Gallery’s chief executive Bettina Korek and artistic director Hans Ulrich Obrist, I was drawn to the sweet treats on offer – dessert buffet tables laden with enormous floral fruity cakes and nougat.

Later, we carried on partying at the newly refurbished Roof Gardens, which is definitely the place to be.

It was a case of “from gown to gym kit” the next day when I did a circuit of the park on my 6.30am run before taking my boys to school.
