Stephen Fry has teamed up with Heads Together in a candid video about mental heath.
The 59-year-old comedian joined forces with the charity - which was set up by Prince Harry, Prince William, and Catherine, Duchess of Cambridge - to support a new campaign spearheaded by the royals to tackle the stigma surrounding mental health.
Stephen - who has previously spoken about his bipolar disorder diagnoses - is seen in the video talking to a psychiatrist, where he says that "talking" about his mental health was a pivotal part of his "healing" process.
He said: "It was very difficult but it was ultimately the healing thing. Talking was really a very strong part of the healing."
To which his psychiatrist Doctor William Shanahan said: "Most people aren't very good at opening up and I think we have to, I certainly have to, to get people to feel that this is going to be a comfortable and helpful time for them. One conversation can make all the difference."
The video comes as part of a series put together by Heads Together which aims to encourage others to voice their struggles after a poll released by the campaign found that men are less likely to talk about their mental health than women are.
Other stars involved in the series - called #oktosay - include model Adwoa Aboah, Rio Ferdinand and Ruby Wax.
One clip sees Adwoa and her mother discuss her attempted suicide and how she managed to beat her battle against depression and gain control of her bipolar disorder.
Another sees former soccer player Ferdinand talk to his agent about how he dealt with the tragic passing of his wife Rebecca Ellison, who died of breast cancer in 2015.
While another clip is based on Ruby as she discusses with her husband about struggling with mental illness and what others around those suffering can do to help them.
