"I had two pregnancies that I lost in the late fifth month," Contactmusic quoted her as telling Prestige magazine.
"And this is so awful because I had to go have surgery when my children died. This is a trauma that you just cannot bear," she added.

She said: "I was in some kind of crazyville. The horrific loss of those people's children caused me tremendous grief. I was relating to this earthquake like some kind of crazy mother.
"In that moment, I was so grief-stricken, and I was really relating to their grief. I had lost children myself. All of that was really heavy upon me. I was really speaking as a heartbroken mother."
