Drew Barrymore pregnant with second child

Everyone's favorite flower child is about to become a mama for the second time.

Drew Barrymore is pregnant with her second child, a rep for the actress confirmed to us on Monday.

The 38-year-old and hubby Will Kopelman are already parents to 1-year-old daughter Olive.

Barrymore, shown above in a loose Vivienne Westwood Anglomania maxi dress -- and with a small baby bump -- at the Los Angeles County Museum of Art's gala on Saturday night, opened up in InStyle's September issue about her desire to have another child.

"I was an only child, and it was lonely," the Flower Films honcho told the magazine.

On being a mom, she said that parenting is "like wearing your heart on the outside of your body."

"It’s the most beautiful, perfect analogy," Barrymore said. "I have anxieties about how much I’d like to get it right, making sure I provide [Olive] with an environment that’s safe, nurturing, and loving. And silly and free, also consistent and grounding. Then I just have the same typical fear every other parent has: Are they going to fall down?"

The pair married in June 2012.
