"I don't want to be the typical pregnant woman, who has to wear a baby-doll dress every day, so we try to keep it funky, sexy and feminine," she says.
Meanwhile Jay-Z is reportedly terrified he'll pass out when his wife gives birth.
"This is his first child with Beyonce and he obviously has no idea what's going to happen," a source told Look magazine. "He even joked he might pass out."
Beyonce's former Destiny's Child bandmate Kelly Rowland will also be present when the baby arrives and has told Jay-Z she'll lend him some support.
Rowland has been attended birthing classes with her best friend whenever she's around.
"It was pretty much assumed that Kelly would be in the delivery room with Bey when she gives birth," the insider said.
"It's obviously something Kelly wants to do."
