The gorgeous pregnant stars showed off their baby bumps Saturday in Los Angeles at a Safe Kids Day event, with Ciara rocking a white shirtdress and Barrymore sporting a navy blue shirt, black pants and ballet flats.
The duo was all smiles as they posed together at the outdoor event, before taking some time to chat.
"Excited About Joining Safe Kids 2 Day!! Together We Can Protect Kids, Prevent Injuries, and Save Lives!," Ciara posted on Instagram prior to the event.
The "Body Party" singer's fiancé, Future, recently spilled the deets on her pregnancy, telling Wendy Williams they are having a boy and that wedding plans are going great, when he appeared on the Wendy Williams Show.
Meanwhile, the Big Miracle star is expecting a baby girl with her husband Will Kopelman. They are already parents to daughter Olive.
Barrymore opened up about being pregnant for the second time back in January, telling Entertainment Weekly, "Being pregnant and having a toddler, as every parent says, is amazing."
"You're very tired, but it's so wonderful. God, it's emotional, but it's the best. I wouldn't want to be anywhere else. My daughter gets all my time, and if I get to sneak out and do some work, I feel really guilty that I'm not with her. I'm also glad that I'm filling up something in myself to give to her. It's good. You just sort of balance things."
