Britney Spears' mother LYNNE has attributed her daughter's recent break-down to post-natal depression.
The pop star was hospitalised at the beginning of the year (08) under a mental health order following months of bizarre behaviour.
And Lynne Spears insists that the singer's problems began after she gave birth to her two children, Sean Preston, three, and Jayden James, two.
But the star's mental health deteriorated further when she split from her husband Kevin Federline in November 2007, leading to a downward spiral in her personal and professional life.
Lynn writes in her forthcoming book Through the Storm: A Real Story of Fame and Family in a Tabloid World, "Having two children within a year of each other would be overwhelming for any woman. She had post-natal depression.
"Added to her broken-hearted spirit over the end of her marriage to Kevin and the enormous pressures of her career, it brought her to breaking point.
"It was hard for me to believe this much-loved daughter was enduring such pain and I couldn't be there to help her heal. I felt hopeless."
