In a statement released to People magazine, the star revealed her new baby's arrival along with the couple's choice of name.
“Happy to announce that today we are the proud parents of our second daughter, Frankie Barrymore Kopelman.”
“Olive has a new little sister, and everyone is healthy and happy!”
Drew announced she was pregnant with her second child last autumn, only a year after welcoming 19-month-old daughter Olive.
The actress revealed the sex of her new addition late last year, telling People magazine: “I’m relieved I’m having another girl. I have everything I need. It’s all about hand-me-downs and room sharing and all that stuff. I’m pretty psyched about that!”
Former wild child Drew has been pictured looking ‘happy and healthy’ throughout her pregnancy, showing off her bump at The Oscars and The Golden Globe awards earlier this year.
She also revealed to Ellen Degeneres that she wasn’t worried about gaining weight during her pregnancy.
She was enjoying her food so much, her doctor warned her to ‘hold back’ a little bit.
‘I was like, really? I thought I was doing great. I still fit into those jeans - they hurt when I wear them -- but I still fit into them. I don't ever pose, 'I'm just so fabulous and I lose it like that.' I want to enjoy the pasta right now! What's 10 lbs?’
