The 38-year-old actress is pregnant with her second child and also has 14-month-old daughter Olive with husband Will Kopelman.
Barrymore, who began her acting career when she was just 11-months-old, thinks her own experiences growing up in the spotlight have been a blessing and given her a strong foundation to deal with public interest in her children, reported Contactmusic.
"Even though I grew up in a different time, when every step you took wasn't recorded, I still went through things in my youth that were totally out there and very much exposed. I didn't know it at the time, but it was a blessing. It prepared me for this world we live in today," Barrymore said.
