Kerry Katona is said to be confident that she can win Brian McFadden in a custody battle, if he tries to take their daughters.

McFadden has threatened Kerry with legal action after a video was released of her snorting cocaine last month.

A source told Now magazine: “This custody fight talk frightens Kerry, but she knows deep down that you have to do a lot more than be filmed taking cocaine to lose your kids.”

The insider added: “Kerry says she doesn’t need the hassle of a custody battle – she’s had enough to last a lifetime. She’d fight Brian if he did try to take the kids, but she knows that won’t happen.”
