Kerry Katona has decided to put her fiancé Mark Croft on a strict new diet.

The 25-year-old, who is currently three months pregnant, spoke to fans as she paid a visit to a sports shop in Warrington.

An onlooker told the Daily Star: "Kerry was in fine form and happily signed autographs for people. She was joking that she is already plotting different ways to shed her post-baby bulge.

"Kerry revealed she has put Mark on a diet of low-fat food and wanted him to get some new work-out clothes. And she giggled and said the only clothes she's buying at the moment will be maternity wear."
