Prince William supports Diana's cause with royal first

Prince William visited with students at a London school this week to support his late mother's anti-bullying campaign -- and became the first royal to speak out against homophobia.

Princess Diana set up the back-to-school program, which is used in thousands of schools today, to help train students how to recognize bullying and seek help.

Prince William and the Diana Award staff taught the group about cyberbullying and he also specifically spoke out against homophobia — a first for the British royal family.

The future Monarch has never publicly addressed LGBT rights but he has privately served alongside a transgender Royal Air Force pilot in the past.

The prince took part in several activities with the kids — including a 'high five' system, which involves students making a list of five people to turn to for help.

A few on the prince's list? Duchess Kate, his younger brother, Prince Harry, and their father, Prince Charles.
