Kerry Katona has reportedly claimed that her husband set up the video in which she is shown taking cocaine.
According to the News of the World, the former Atomic Kitten singer told her friends that Mark Croft had planted a camera in their bathroom.
The newspaper reported that Katona allegedly said: "Mark's my best friend and he's betrayed me. That's the biggest…sick thing he could do. And this is the hardest thing I've ever had to go through."
She added: "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."
However, Croft apparently denied the claims to friends that he had made the video, saying: "Kerry accused me but I wasn't even there. People are feeding Kerry with lies and she's believing them.
"I'm sick of walking on eggshells all the time because of Kerry's temper. I've just got to look after myself now."
Katona previously said that she was "tricked" into taking the drug.
