Kerry Katona is best known as a media personality, and since bursting onto the scene as part of girl band Atomic Kitten, she has gone on to present, write and be a regular feature in the nation’s media.
After an uneasy childhood in care she found fame with the band, who secured four Top 20 singles in Britain and had huge success in Asia, securing a number one hit with Cradle.
Katona married ex-Westlife band member, Brian McFadden, and they went on to have two children.
After leaving Atomic Kitten, Kerry made the successful transition into a television career, starring in several of her own reality shows including, My Fair Kerry, Kerry Katona: Crazy in Love, Kerry Katona: Whole Again, and Kerry Katona: What's the Problem?
After the collapse of her first marriage, Katona had two more children with now ex-husband Mark Croft before their turbulent relationship finally ended in 2010. Since their split, Kerry has gone onto rebuild her personal life and professional career.
