Her daughter, Olive, turned 1 last month, and Drew Barrymore is already looking to get pregnant again.

Last night on "The Tonight Show with Jay Leno," Barrymore, 38, spoke about her adorable child and when Leno asked if she'd want more babies, she was quick to answer.

"Very much," she said. "Right away, yes."

Right away? Well, Barrymore grew up an only child and doesn't want her daughter to have the same experience.

"I want to be the Griswolds," she said about wanting a huge family. "I want the kids in the back rolling their eyes at mom and dad. I want Rusty and Audrey, theme parks and the whole nine."

The "50 First Dates" actress had Olive with husband Will Kopeland after the two were married in June 2012. Barrymore added that she and Kopeland are enjoying time with their little one before the next baby.
