James Middleton and Alizee Thevenet at Lady Gabriella's Wedding

By Kayleigh Roberts published 18 May 19

This weekend, the Queen's cousin, Lady Gabriella Windsor (or "Ella," as her close, personal friends call her) married Thomas Kingston at St. George's Chapel in Windsor. The venue is the same place where Prince Harry and Meghan Markle wed almost a year ago and the guest list had a fair amount of overlap too.

In addition to senior members of the royal family, like Prince Harry, Queen Elizabeth, and Prince Philip, Lady Gabriella's wedding was also attended by several members of Kate Middleton's family, including her mother and father, Carole and Michael Middleton, her sister Pippa and her husband, James Matthews. Kate's younger brother, James Middleton, also turned out for the royal affair and he brought his girlfriend, Alizee Thevenet, as his date.
