Dwayne 'The Rock' Johnson recently revealed his secret battle with depression left him 'devastated and crying constantly'.

He has spoken about the 'vulnerability' men feel when talking about mental health as he appeared on Lorraine on Friday.

The actor, 46, who welcomed his daughter Tiana with his fiancee Lauren Hashian two weeks ago, candidly discussed his own story and how he 'bottled his feelings in' as a teenager.

He told Ross King, "Depression doesn't discriminate and I thought that was an important part of the narrative if I was going to share a little bit of my story of the past.

Regardless of who you are or what you do for a living or where you come from, it doesn't discriminate, we all kind of go through it. If I could share a little bit of it and if I could help somebody I'm happy to do it.

The key thing that I found was the most important thing about that, talking about my past in terms of depression, is the revelation and for us to be OK and embracing… especially us as guys, as men.

There's just a DNA, a wiring in us and a constitution that oftentimes doesn't let us talk about when we're scared or vulnerable or things like that.

It's kind of like what's been deemed as 'toxic masculinity'. You've got to talk about it and you're not alone. I was an only child and I kept that bottled in, deep, deep. It wasn't good, so happy to share my story."

The wrestling legend, who is known for his tough guy exterior, candidly discussed the darkest time of his life, two months after he revealed he had witnessed his mother attempt suicide when he was 15.

The Moana star, who is promoting his latest film Skyscraper, previously told : 'Struggle and pain is real. I was devastated and depressed.

"I reached a point where I didn't want to do a thing or go anywhere. I was crying constantly."

The ‘Rampage’ star managed to overcome his mental health battle, and recently welcomed his third child, a daughter named Tiana, into the world with his partner Lauren.
