Musician Aja gave birth to Gia James and Coco Rae on Tuesday (28Mar17), with Gia making her arrival first at 8am, weighing 6lbs 2oz, before Coco arrived at 8.12am, weighing 6lbs.

“These have been the most magical/restless/overwhelming/rewarding hours of our lives. We couldn’t be more in love with our girls,” the couple told People.

The pair have something of a reputation for choosing unusual names for their offspring - they are also parents to four-year-old daughter Arrow Eve. And speaking about the inspiration for monikers for the twins, Dan told the outlet: "Gia because Aja is part Italian and her brother’s name is Gino. We wanted a real Italian name. James is Aja’s dad’s first name. Coco Rae just because we liked the sound of it!"

Dan also took to his Instagram to reveal the first picture of his new arrivals, captioning it: "Welcome to this beautiful world Gia James and Coco Rae‬."

The twins have already made their mark on big sister Arrow, who has relished having siblings.

“Arrow has been doting over her sisters. She keeps telling us that she will be the best babysitter for them, ‘even when they are all grandmas,’” the couple added to People.
