Kerry Katona is facing a custody battle from her ex-husband Brian McFadden for their two children together.

The former Westlife singer will apparently use Katona’s own MTV series ‘Crazy In Love’ as evidence that she is not a suitable mother to their daughters Molly, six and Lilly-Sue, five.

Katona, who has just given birth to her fourth child, has been widely reported to have struggled with drugs and alcohol issues during her tempestuous second marriage to Mark Croft.

A source close to McFadden, who now lives in Australia with singer Delta Goodrem, tells the News Of The World, “Those poor girls need stability because they've lived a rollercoaster ride with Kerry for too long.

“You only have to look at her show and see the mess she's in. Brian can give them the upbringing they deserve."
