Kate Middleton and Prince William Lead Celebrities in a 'Mental Health Minute' Broadcast

Kate Middleton and Prince William are encouraging open conversations about mental health.

On Friday, the royal couple joined well-known faces from soccer star David Beckham to singer Anne-Marie and chef Jamie Oliver in a 60-second broadcast urging U.K. citizens to continue to help others and carry on conversations about mental health struggles as the country comes to an end of its Mental Health Awareness Week.

In the PSA, William, 38, said, "It would be great to keep talking," as Anne-Maire added, "To a loved one, friend or colleague — let's keep making the conversation accessible."

And Kate, 39, then added, "Because our mental health binds every single one of us together."

Beckham, 46, summed up the message's key themes, saying, "Taking time to reflect through the most challenging of years."

The Mental Health Minute, which also featured actors Joanna Lumley and Charles Dance, was broadcast on radio station around Britain at 10.59 a.m. local time. The minute-long message is in support of Shout 85258 – the 24/7 text messaging helpline developed by the couple's Royal Foundation and is the latest element of their work on the issue this week.

The combined audience of the simultaneous radio broadcast was estimated to be around 20 million. The script was penned by poet and mental health activist Hussain Manawer, who also appeared in the broadcast.

Leading up to Friday's broadcast, Beckham urged people to turn on their radios to tune in. "This year more than ever, it's important that we all keep talking," he said in a video shared on the Shout 85258 Twitter.

On Thursday, William and Kate visited Wolverhampton, in England's Midlands, and toured some projects helping those with mental health and also enjoyed some games with children.

"Come on, Catherine!" William said as he encouraged his wife to join his game of ping-pong. "Catherine is really good at table tennis."

As she grabbed her paddle, the couple were clearly in their element. "This could go on for hours," said William. "Talk amongst yourselves!"
