Never Been Kissed actress Drew, 39, and singer Ciara, 28, both lent their support to Safe Kids Day 2014 - the 2nd annual event to raise awareness and funds to prevent childhood injuries in the US.
Arriving at The Lot in California's West Hollywood, Drew dressed her extended belly in a loose-fitting navy blue shirt, black maternity jeans and sensibly opted for flats with black ballet pumps.
Drew is expecting her second daughter with husband Will Kopelman. Their first child Olive was born on September 26, 2012.
Meanwhile, R&B artist Ciara is expecting her first child with fiancé Future.
She announced her pregnancy in January, during an interview with US chat show The View.
She looked stunning in an oversized white shirt worn as a dress, teamed with red canvas flats.
'Love Sex Magic' singer Ciara celebrated her baby shower at a bash in Los Angeles last month with the help of celebrity friends including Kim Kardashian and Kris Jenner.
Both Drew and Ciara are due any day now... Deep breaths, ladies!
