The Gunns have had three children: Francesca, Melissa and Angus. Melissa is a model, while Angus is a footballer and plays in goal, like his father. On the books as a youth player at Norwich City, in October 2010 he was selected for England under-16s, a full year ahead of the age group. In July 2011, Angus joined Manchester City; he has "sharp reflexes and strong wrists" and an "ambitious streak". Angus rejoined Norwich on loan in June 2017, and now plays for Southampton. He also plays for the England under-21 football team.
