The trio sat together in the stands as England faced off against Wales. To the ordinary royal watcher, it sounds like a great event, right? Until you find out the brothers were rooting for different teams.

This month marks the official end of maternity leave for the Duchess of Cambridge. The 33-year-old's first solo appearance since giving birth took place earlier this month at the Anna Freud Centre, an organization that helps young people with mental health concerns.
