The former TV star has struggled with an addiction to booze – but gave up drinking when her husband, lawyer Robert Altman, begged her to stop.

She tells U.S. TV show The Insider, "My husband asked me ... 'Can't you just stop this for the children and for me?'"

The 56-year-old adds, "I was so good at hiding it too... Brilliant."

The TV icon, who has been sober for nearly ten years, cites her two children as the catalyst for her change - prompting her to seek help through a rehab facility in Washington, D.C.

She explains, "I needed help - I begged God in heaven to help me figure this out."
