The 33-year-old royal isn't a fan of the social media site, according to actress Megan Mullally, who met the Prince during a trip to the United Kingdom.

Speaking on CONAN, she said: "First of all, he's an amazing athlete. He's tall, he's cute, I don't care that he's losing his hair. It doesn't matter.

"He said that he didn't like Twitter because he thinks it is mean. They're watching 'Game of Thrones.'"

Meanwhile, the Duke and Duchess of Cambridge are reportedly keen to have a "constructive dialogue" with Twitter and Facebook bosses in order to stop cyberbullying.

A royal aide said: "Their role as parents is definitely shaping their perceptions on the issues. As parents themselves they want to speak out and see what more can be done for young people who are victims of cyberbullying and all forms of bullying."

The royal couple have always been strong supporters of stamping out bullying as a result of stigma surrounding mental health.

In a statement released previously, the mother-of-two said: "I feel strongly that young people and parents need to know that they can ask for help.

"Just as with physical health, we need to act early to provide support when a child is faced with emotional difficulties."
