Jamie Lee Curtis confesses that she deeply regrets some of her parenting decisions.

The actress raises two children with her husband Christopher Guest, Annie and Thomas.

Jamie, who is the daughter of Hollywood legends Tony Curtis and Janet Leigh, upsets herself when she emulates her parents' behaviour.

"I feel like a failure as a mother a lot, because despite my best efforts, I have replicated parts of how I was parented [that I didn't want to]," she told the October edition of Good Housekeeping magazine.

"Even though I vowed not to and felt like I was doing it so differently, in many ways I repeated some of the same problems."

The 54-year-old star is extremely proud of her sobriety.

Jamie has been clean now for 13 years.

"Getting sober was the single bravest thing I've ever done and will ever do in my life," she shared.

"Being courageous enough to acknowledge it privately with my family and friends. Working really hard at solidifying it, getting support around it, and being healthy. And then talking about it publicly. That is the single greatest accomplishment of my life."
