Houston: 'Crazy Bobby Cut My Head Off In Photos And Spray Painted The Walls'

In her first in depth interview since divorcing the fallen R&B star, the singer tells Oprah Winfrey her "crazy love" for Brown left her beaten down and abusing cocaine and marijuana.

In the much-hyped TV exclusive, which airs in America on Monday (14Sep09), Houston reveals she tried to be the perfect wife and for a long time she and Brown "fought hard (and) loved hard".

But she struggled to deal with her ex when he drank and became "mean".

Houston insists Brown never physically abused her, but he would spit on her and terrify her with crazy behaviour.

She adds, "He had such hate in his eyes for me, because I loved him so much."

She recalls Brown cutting her head off in pictures and drawing 'evil eyes' on their bedroom walls with spray paint.
