In a ground-breaking new video, watch as British royal Prince William connects with Lady Gaga through Apple's FaceTime to talk about issues pertaining to mental health. The musician, who suffers from post-traumatic stress disorder (PTSD), spoke out about her suffering and in support of Prince William's efforts to eradicate the social stigma associated with the disease through the Heads Together initiative.

"There's a lot of shame attached to mental illness, you feel like there's something wrong with you," said Lady Gaga. "The best thing that could come out of my mental illness was to share it with other people and let our generation, as well as other generations, know that if you are not feeling well in your mind, that you're not alone." The sentiment for open conversation was shared by Prince William who said, "It's so important to break open that fear and that taboo, which is only going to lead to more problems down the line."
