The Duke of Cambridge has teamed up with pop superstar Lady Gaga to encourage people to open up about their feelings and bring an end to the "shame" of talking about mental health issues.
In a video watched by around 15,000 people live on Facebook, William and Lady Gaga chatted about how important speaking freely about mental health can be in helping to shatter the stigma around it.
The Duke said: "It's time that everyone speaks up and really feels very normal about mental health, it's the same as physical health. Everybody has mental health and we shouldn't be ashamed of it and just having a conversation with a friend or family member can really make such a difference."
William, who with his brother Harry and the Duchess of Cambridge have championed the Heads Together campaign, has has called for an end to the "stiff upper lip" culture, saying he wants Prince George and Princess Charlotte to be able to talk about their emotions.
It comes after Prime Minister Theresa May praised Prince Harry for his bravery in revealing that he sought counselling to come to terms with the death of his mother, Diana, Princess of Wales.
