Working right up to her due date!

Drew Barrymore attended the The Big Picture event at Caesar's Palace as part of CinemaCon yesterday, and the actress looked adorable in a bright yellow dress before changing into a patterned maroon maxi for The Big Screen Achievement Awards.

The beautiful mama-to-be was in Sin City to promote her new film Blended with co-star Adam Sandler, but she also took the opportunity to take home Female Star of the Year award.

The Big Miracle star and husband Will Kopelman are set to welcome their second daughter any day now, so this is most likely her last public appearance before she pops!
