Both Lady Gaga and Prince William have been fierce advocates about speaking openly about mental health and now we are getting the chance to see the unlikely pair talk even more about the topic.

Watch above as the two chat on Facetime about the importance of mental care. Gaga shared her love for Heads Together, the mental-health campaign spearheaded by the Duke of Cambridge along with his wife Duchess Kate and brother Prince Harry, while the Prince expressed admiration for the singer recently opening about her struggles and how it's changed her life.

"It's really important to have this conversation," William told the star. "It's time everyone speaks up and feels very normal about mental health. It's the same as physical health. Everybody has mental health and we shouldn't be ashamed of it." Gaga added, "We are not hiding anymore, we're starting to talk, and that's what we need to do really."

In December, Lady Gaga shared she was suffering from PTSD which drew controversial criticism from Piers Morgan and saw the star challenge the TV host to an interview/"debate" on the topic.

Keep the conversation going with a revealing Fuse interview where Sinéad O'Connor speaks about why she and Miley Cyrus are "catalysts for mental health discussion":
