Jecca and William's relationship is one of the most complicated on the list. William reportedly met Jecca in 2000 while he was on a gap year from Uni. He stayed on a Kenyan ranch owned by Jecca's parents at the time and the ex-couple even carried out a "pretend engagement," E! reports. Jecca was also rumoured to be the cause of Kate and William's split in 2007 due to his feelings for her, but nevertheless, he chose Kate.
Craig married Jonathan Baillie in 2016, and Prince William was amongst the guests.
