Emma completed her look with Dolce and Gabbana sunglasses, silver stud earrings and dark shades.

The couple, who married in June 2013 at their beautiful Longleat home, welcomed their first child John in October 2014.

After a pregnancy battle, the couple welcomed their second child, a son Henry, through a surrogate in Los Angeles in December 2016.

Emma told the Daily Mail at the time: ‘We’re just ecstatic. His arrival has completed our family and brought us so much happiness.’

Ceawlin added, “I never imagined I’d be fathering John’s little miracle brother in West Hollywood.”

“It is a marvel of modern scholarship that the Longleat Bath family has been augmented (at least for now) by Emma and I having a much-loved son, aided so crucially by a wonderful surrogate in California, to expand our family.”

It comes after Emma looked stunning in a sheer black dress when she was spotted at Chiltern Firehouse last month after attending a conservation ball alongside King Charles and Queen Camilla.

The event was hosted by British Vogue editor-in-chief Edward Enninful and self-portrait founder and creative director Han Chong, along with model Emily Ratajkowski to celebrate British creativity.
