Sinead O'Connor has penned an open letter to Prince Harry as she said she is able to identify with his grief.
The 54-year-old singer has said that she was "bowled over" by his Apple TV mental health documentary, The Me You Can't See.
In the documentary, the Duke of Sussex opens up about grappling with his grief over the death of his mother, Princess Diana, in a car crash in 1997. Sinead's own mum tragically died when she was just eighteen.
Addressing the documentary in Ireland's Sunday Independent newspaper, she said: "As someone who has trauma-related mental health struggles, I wanted to let you know how bowled over I am by your Apple TV series. You're slammin' it, to use a musical term. You just keep shining on through."
In the documentary, Prince Harry is joined by Oprah Winfrey and other celebrities as they speak about their experiences with mental health.
Opening up about why she had been so moved by the series, the songwriter said: "I'm writing this because you and I have something in common Harry. I also lost my mother in a car crash... I do know something of the grief you've been brave enough to share in the public arena.
"It's a shock that takes years to come out of, when someone dies so violently and suddenly. It's a lifetime's recovery."
Sinead also explained that she was grateful that Prince Harry had spoken about his grief so openly, explaining: "I really identified with you when you shared the rage and anger you felt at the time of your mother's passing. I was the same. I'm sure we all were, any of us who ever lost someone in that sudden way.
"Transcending that grief as you've done by sharing it, cuts through a lot of garbage. And a lot of us appreciate what you're doing."
She also insisted that his mother would have been very proud of him, writing: "When so many of us see the work you're doing for people who experience mental health struggles, we see you stomping on stigma. And we're all delighted for you.
"Most importantly, we know how proud your mama is of the incredible young man you are."
