Prince William, Duke of Cambridge and his wife Catherine, Duchess of Cambridge attend the first Global Ministerial Mental Health Summit, co-hosted by the government and the Organisation for Economic Co-operation and Development, in London yesterday.
The 10 October marks World Mental Health Day, which Kate, William and Harry have shown an interest in for the past couple of years, as part of their Royal Foundation charity.
It's their first joint public engagement since Prince Louis' birth.
The Mental Health Summit will see political figures, leading academics and policy-makers from around the world come together with one common goal: better mental health for all.
Vargas handed over a brush to Kate and William, though both were a bit hesitant to partake.
The royal couple arrived to attend multiple presentations on case studies of active mental health programs and also met with young people to speak about their experiences with mental health.

Prince William then teased his wife, saying "It's nearly ruined the picture", after she added a white stroke to the painting, but later joked: "no, this is probably how you ruin a picture", as he added his own mark.
The royal donned a chic lilac Emilia Wickstead dress, which she teamed with a pair of pointed nude stilettos and a matching handbag.
The event is the Duchess of Cambridge's second royal engagement since returning to work following the end of her maternity leave.
In the lead-up to hosting a Marathon for Mental Health in the United Kingdom in 2017, Prince Harry revealed he'd sought counselling in his early 20's after two years of what he labelled "total chaos" following the death of his mother, Princess Diana.
Welcome back guys, we've missed you!
