Christina Aguilera has opened up about her struggle with depression, insisting her feelings of sadness are "always right below the surface".
The Dirrty hitmaker speaks candidly about the disorder in a new Behind The Music special on U.S. TV network VH1, admitting she's found creative inspiration in her darkest moments of depression.
She explains, "I do battle with depression. It's something that is always right below the surface. And it's almost seductive to go to a place of sadness and darkness... I'm truly thankful for the darkest times in my life.
"I definitely don't choose the safe way of living or expressing myself but I wouldn't have it any other way."
Behind the Music: Christina Aguilera is set to broadcast on 13 June (10) in the U.S.
