"I'd be lying if I said I don't have any regrets. I was filmed snorting cocaine in my bathroom by a secret camera and I hold my hands up and admit it," the Sun quoted her as telling the Love it! Mag.
Katona said: "I have taken drugs in the past and I will try to make sure I don't take them again. But I honestly can't hold my hands up now and say I'll never take drugs again because I don't know what will happen.
“But I do not have a drug habit. It was a one-off and I'm getting help to try to make sure it doesn't happen again. It's not like I can afford a drug habit anyway! The courts give me a weekly allowance and I have to show receipts for everything I buy."
And the 29-year-old mum-of-four also tried explaining her drug episode. She said: "I was in the middle of a mini-meltdown after Mark was accused of touching up a stripper. A guy we knew came round and put a secret camera in my bathroom and offered me a line. Stupidly, I took it.
"But it was a one-off and, as I said, I'm getting help. I can ring my therapists, Nik and Eva Speakman, any time of the day or night and I've been to the Priory."
Katona also denied reports that she was a heavy drinker and said: "It made me slur my words and people assumed I'd been drinking. I wasn't in control of my emotions. I'm not advising anyone to stop taking their own medication but I was in such a depressive state on it I'm better without."
