Congratulations to Drew Barrymore -- the actress just welcomed her second baby girl with husband Will Kopelman!

"Happy to announce that today we are the proud parents of our second daughter, Frankie Barrymore Kopelman," Barrymore and Kopelman tell PEOPLE in a statement. "Olive has a new little sister, and everyone is healthy and happy!"

Indeed, baby girl Frankie has joined the proud, second-time parents and big sister Olive, 19 months -- and the family couldn't be any happier.

Barrymore revealed that she was having her second girl in December, and she couldn't hide her excitement for having another child immediately following the first.

"I was an only child, and it was lonely. Some people thrive on the independence, but I want my kids to have other kids around," she told InStyle (quote via PEOPLE) last September. "Maybe two kids so they can run around life together, roll their eyes at their parents together like Rusty and Audrey Griswold from [National Lampoon's] 'Vacation' series."

While Olive and Frankie may have to wait a few years for the eye-rolling, we're sure that the two sisters will bond quickly, and Mom soon may be eating her words.

And speaking of eating, Barrymore (who looked radiant during her pregnancy), insisted that she ate everything in sight, telling Ellen DeGeneres that she "just wants to enjoy the pasta right now."

Well, all of that hard work just paid off. The Kopelman family has a beautiful new bundle of joy.
