"I think if my bump was a little bigger, this might not have worked," Ciara -- who presented at the AMAs -- told ET's Sophie Schillaci of the daring style. "I'm super excited about my dress and very happy and comfortable."
As for her 2-year-old son Future's reaction to becoming a big brother, Ciara said that he "can't wait" and is "already obsessed with babies."
"He rubs my belly and he says, 'Hi baby. I love you, baby,' ... and then he puts my shirt down and says, 'Bye, bye baby.' So, that's his own thing," she gushed. "He sees a baby walking, smaller than him and walking -- it doesn't matter, it's a baby. So, he goes, 'baby' and he looks at me and he goes, 'Mama, baby' --and he tries to pull my sweatshirt up."
Ciara also shared that she and Wilson have already picked out a name for their baby-to-be, and opened up about the couple's pregnancy announcement that fell on her birthday. "It was kind of a cool gift, you know, one first for us to be able to have, my husband and I," she recalled. "I think for my fans to be able to share that gift on my day was also special too. It made my birthday one of the most memorable birthdays of all."
