Kate Moss was accompanied by her husband, Jamie Hince, to attend the wedding of her personal assistant, Fiona Young, at Camden Town Hall in London on Saturday. Kate greeted the bride, who wore a light pink dress, with an enthusiastic smile and mingled with fellow wedding guests, which included Sienna Miller. While Kate had Jamie by her side, Sienna attended the nuptials solo, though her ex-boyfriend, Rhys Ifans, was also a guest. Sienna and Rhys ended their relationship in 2008, and she has since moved on to become a mom to her 1-year-old daughter, Marlowe, with her fiancé, Tom Sturridge. She was not the only one to encounter a former flame at a wedding this weekend. Prince Harry attended the marriage celebration of pals Lady Melissa Percy and Thomas van Straubenzee, and both his ex-girlfriend, Chelsy Davy, and current love interest, Cressida Bonas, were guests of the Northumberland, England, nuptials as well.
