Katona: 'Price's marriage is a sham'

Kerry Katona has criticised Katie Price's marriage to Peter Andre, calling it a "business arrangement".

The reality TV star told OK! that her own union with Mark Croft has more longevity.

Asked whether she believes Price will withstand her reported marital problems, she responded: "I think it's more of a business arrangment than anything else. [Me and Mark] are stronger. We'll be together always."

Katona also defended her husband's recent admission that he fathered a secret 'love child'.

"It bothers me I have to defend Mark all the time. I know Mark and how romantic and sickly sweet he can be," she said.

"If Mark cheated on me I’d get rid of him straight away. I mean, look at him - he’s lucky to have me!"
