How cute is she?!

Drew Barrymore had all eyes on her when showed off her adorable baby bump with a long-sleeved polka dot dress at the Hollywood Stands Up To Cancer event hosted by Reese Witherspoon and her husband Jim Toth on Tuesday night.

The free-spirited star, who is already mother to daughter Olive, accessorized her fun frock with a yellow clutch. In November, the Going the Distance star and hubby Will Kopelman announced their second pregnancy and confirmed they were executing a baby girl.

Drew admitted recently that she has no intention of cutting back on her snacks as she is enjoying embracing her figure.

Recently, the 38-year-old told Ellen DeGeneres that she planned on fulling indulging on her pregnancy cravings: "I just eat everything I want, which isn't healthy. I'm bigger this time than my first time. My doctor the other day was like, 'Yeah, so I think maybe pull back. A little bit.'"

She went on, "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?"

Drew joined Heidi Klum, Selena Gomez, Christina Aguilera, Gwyneth Paltrow and Diane Kruger at the glittering charity event.
