Singer Brian McFadden is angry at his ex Kerry Katona for using their children as "pawns" in her reality TV shows. The ex-Westlife member, who married the Atomic Kitten star in 2002, had lost two legal battles to regain custody of their daughters, eight-year-old Molly and Lilly-Sue, seven.

McFadden maintains that he is mad about the way his ex is raising their children. He said that they should not be allowed to be filmed for Katona's U.K. reality program.

"It really upsets me when she uses the kids in her TV shows. I don't like them being pawns in a story," he said.

In June, Katona apologized to her fans for her attitude in TV documentary "Kerry & Me". On the show, she was seen smoking and threatening to "knock out" her daughter Molly.
