The royals joined other mental health charities, who have representatives running a London Marathon to spread awareness and spark conversation surrounding mental health.

"Let's get our #HeadsTogether to change the conversation on mental health @Heads_Together," Kensington Palace’s official Twitter handle captioned a photo of the trio wearing teal headbands.

In the PSA, the royals are featured chatting with the charity workers about their important cause.

"Mental health is just as important as physical health," Middleton says in the clip.

But the tone of the video wasn’t somber at all. As Kate, William, and Harry tried posing for photos, the father of two suggested they try a serious pose, but his brother and wife have a case of the giggles.

The sweet candid moment comes after weeks of public events and appearances. William and Kate recently returned from their Royal Tour of India and Bhutan and last Friday they hosted President Barack Obama and First Lady Michelle Obama on their visit to London.
