The premiere episode of Kerry Katona's new reality TV series has given new insight into her bizarre marriage to former cab driver Mark Croft.

The couple allowed TV crews into their lives to film MTV documentary Kerry Katona: Crazy in Love to prove that despite rumours of a troubled relationship, their marriage is stronger than ever.

But their plan may have backfired, with the pair spending much of last night's debut programme telling one another to "shut your face" and "shut your trap".

Making a splash: the pair regularly told one another to 'shut your face' during last night's show

"I'm romantic, I often just say to her spontaneously let's go out and get a meal. Kerry's never took me out for a meal, she doesn't appreciate the things I do for her.

"I show my affection and love for you and you just show me hatred."

In one scene, the couple discuss why they love each other as they lie in bed.

Mark says: "You make me laugh, you're kind, you spoil me, you did have big tits but they've gone south at the minute haven't they. They have darling and we have talked about you getting a boob reduction.

In an apparent effort at humour, he then says: "You're not very motherly are you so I can't say that. You're always off your head on drugs."

For her part, Kerry says: "When I met Mark, I knew I'd found my soulmate. He's good to me, I'm a bitch."

Kerry is also filmed going to London to appear on Friday Night With Jonathan Ross.

While getting ready for the Jonathan Ross show, she is seen guzzling a glass of white wine and saying: "I could do with a cigarette. I would like a cigarette."

She also admitted: "I have the odd cigarette here and there. It is an addiction and it's my own fault and my willpower's not good enough."

However, the worst scenes from the new programme may have been left on the cutting room floor.

Reports claim the show's camera team discovered Croft regularly cheats on Kerry and frequently calls her abusive names.

Heavily pregnant Kerry was also allegedly seen smoking 20 cigarettes a day.

A source told the News of the World: "It's all an act when Kerry says how happy she is. After seeing them all day for weeks, I think their marriage is pathetic."
