The Duke and Duchess of Cambridge are contributing to a mental health project led by Love Actually director Richard Curtis.
Kate and William launched mental health campaign Heads Together with Prince Harry in 2016, which aims to dismantle the stigma surrounding mental health issues by encouraging open conversations about psychological illness.
Curtis - who co-founded Comic Relief - has previously spoken about dealing with his grief after his sister's suicide following her 25-year battle with mental health issues in 2009.
According to ITV News, Kate welcomed Curtis into her home at Kensington Palace this week, where it is believed they discussed their new initiative.
Speaking about his loss at a Public Health England Conference, Curtis has said: "I was so privileged and we had so much money and so much access and still couldn’t do anything.
"I can't believe what it must be like for someone whose relatives aren’t in that situation and they have nothing."
The Notting Hill screenwriter suggested that society has failed to focus on mental health, claiming that there was a lack of resources for those in need, such as beds.
Curtis's feminist activist and writer daughter Scarlett has also spoken publicly about her struggle with anxiety and depression. She recently curated a collection of essays, stories and poems from inspirational people for her latest anthology It's Not OK to Feel Blue (and other lies) which examines mental health.
It aims to tackle the mental illness epidemic, and provide a reassuring voice that tells readers they are not alone. She previously published Feminists Don't Wear Pink with Keira Knightley.
