London, Jan 14 (ANI): Drew Barrymore has revealed that she is a fiercely protective mother, and blames it on her troubled childhood, which left her in rehab for substance and alcohol abuse at age 13.
The 37-year-old actress, who has a three-month-old daughter Olive with husband Will Kopelman, asserted that she will literally fight like a lion to keep her family happy and intact.
She acknowledged that there is a possibility that she wouldn't have been this way if she had had a great family growing up, the Daily Mail reported.
Barrymore added that the best thing about being a mum is how it makes you a better person everyday. (ANI)
