London, Sept 6 : A troubled Kerry Katona has been at loggerheads with hubby Mark Croft and has accused him of setting up her coke snorting video, it has emerged.

The News of the World quoted a distraught Katona as telling her friends: "This is betrayal by my husband.

"I know he''s done it. I know it''s him. I''m now wary of my own husband. All I had was my Marky, he was the only one there, he was the one I was trusting. Now I don''t know who to trust, he was my best friend."

She added: "Mark''s my best friend and he''s betrayed me. That''s the biggest f***ing sick thing he could do. And this is the hardest thing I''ve ever had to go through."

The former Atomic Kitten alleged that Mark was hungry for group sex.

She said: "I''m a bitch to him, I have him running around like a blue a*** fly, but I''ve always had this feeling about Mark. . . you know, the threesome and all that kind of s***. It''s like he gets off on it.

The 29-year-old said Mark reminded of maniac Dave Wheat who once lived with her mum Sue.

"That''s psychotic - and that''s why I''m scared. I know he won''t let anybody else have me. I''ve lived with a f***ing psychotic when my mum was with Dave Wheat. To do something like that is seriously wrong."

Katona also blamed her drug habit on Mark.

She claimed: "It wasn''t ME taking them, that''s what HE''S like. Everyone thinks it''s me, but HE hides it around the house and everything." (ANI)
