Boyd, 31, is one of six people the royal couple will reportedly choose to be godparents. The names of those people are expected to be revealed at Prince George's christening on October 23.
Boyd was a classmate of William's at Eton College. He also attended St. Andrew's in Scotland with the royal couple.
During a 2002 fashion show featuring Kate, William reportedly whispered to Boyd "Wow, Kate's hot." A shirtless Boyd also strutted his stuff on the catwalk with Kate during that show. You can see a photo here >
