Meghan Markle and Prince Harry will once again work closely with Prince William and Kate Middleton.

The royal couples will be teaming up for a mental health initiative. The Sussexes and the Cambridges will be launching Shout, a new crisis hotline that will offer immediate support to those in need via text messages.

Prince William explained their latest venture and said that Shout is a new text line that will provide advice and support to people in need during difficult times. The Duke of Cambridge also said that Should would operate 24/7.

“It operates 24/7, and it connects people to trained volunteers who provide help at a time when it is most needed, enabling them to move from crisis to calm and to find longer-term support,” he said.

Shout will be available in the United Kingdom for free.

Royal correspondent Victoria Murphy revealed that Prince Harry, Markle, Prince William, and Middleton have been working on their newest project for months. The Royal Foundation, which they are all a part of, also donated roughly around $3.9 million to the Shout, which is its biggest investment to date.

It has also been revealed that Markle and Prince Harry met up with Shout volunteers secretly and photos from their visit were made public today. In the photo, the Duchess of Sussex is wearing a blue coat with floral embellishments over what appears to be a form-fitting black dress or t-shirt. Prince Harry, on the other hand, wore his signature grey suit to the meeting.

According to Town & Country, the launch of Shout suggests that even though the Sussexes and the Cambridges now operate in different households, they will still work as a team for the Royal Foundation.

“Over the last few months, Shout has started working quietly behind the scenes. Harry, Meghan, Catherine, and I have been able to see the service working up close and are very excited for its future,” Prince William said.
