The actress showed off her big baby bump at two different events during Las Vegas' CinemaCon this week.
Sporting a yellow short-sleeved dress, the mother-of-one looked radiant at Warner Bros. Pictures' presentation held at Caesars Palace on Thursday. The actress styled her long locks in loose waves and sported natural makeup for the event, where she promoted her upcoming movie with Adam Sandler, "Blended."
Later in the day, Barrymore wore a floral gown to receive her Female Star of the Year award at CinemaCon's Big Screen Achievement Awards, which was also held at Caesars Palace in Sin City.
The "He's Just Not That Into You" star went for a bolder floral ensemble, styling her hair straight and parted to the side, and completed her look with a dark red lip paired with smokey eyes.
We're loving Drew's maternity style, and we can't wait for her little bundle of joy to get here!
The baby will be her second with husband Will Kopelman. They welcomed daughter Olive in September 2012.
