She is the daughter of Princess Diana's sister, Cynthia Jane Fellowes, making her William's cousin. It's been reported that she and William are "close," and choosing her to be Charlotte's godmother was another way to honor Princess Diana.

He grew up on the Sandringham estate in Norfolk, and is one of William's best friends. In 2013, he married Rosie Ruck Keene, and William served as an usher.

Julia is the head of the Child Bereavement charity in the UK, and was a good friend of Princess Diana's.

James attended Eton College in Berkshire, England, with Prince William back in 2000. He lives near Anmer Hall, Kate and Will's country home, in Norfolk with his wife Laura.

Emilia is also one of Kate's best friends, and the two attended Marlborough College together. When Will and Kate briefly split in 2007, the ladies jetted off to Ibiza together. Emilia currently runs an interior design company, and it's been reported that she helped Kate redecorate Kensington Palace and Anmer Hall. Her husband, David, also attended Eton College with Prince William.

Thomas is one of William's closest pals, and served as a key usher along with James Meade at Will and Kate's wedding in 2011. He also gave a toast at their wedding following Prince Harry's, and attended Ludgrove prep school with William.

The Olympic equestrian is one of William's cousins and the daughter of Princess Anne. She is close friends of the royal couple, and is married to former Rugby player Mike Tindall.

The 25-year-old is the son of the duke of Westminster, who also happens to be one of William's godparents. Earlier this year, he inherited $8.3 billion and the title of the seventh duke of Westminster.

Oliver is a friend of both Will and Kate's, and attended St. Andrew's University with them in 2003.
