Westlife star Brian McFadden has been blamed for former wife Kerry Katona's descent into drink and drug hell. The 25-year-old split from her Irish crooner husband in 2004 and he has subsequently been dating Australian singer Delta Goodrem. Katona confesses she found it so hard to accept the rejection she briefly found comfort in unhealthy addictions and checked into rehab three times. She says, "Drugs and drink provided a mask for me to hide behind. "They meant I could pretend to be the bubbly Kerry who everyone loved." The recovered former Atomic Kitten star is currently expecting a baby with fiance MARK CROFT.
