Pregnant celebrities have made the streets their own maternity runways, and Jessica Biel is no exception as she rocked a casual outfit that fully displayed her baby bump.

Jessica Biel and her baby bump was snapped on Wednesday in New Orleans on the set of her new film, "The Devil and the Deep Blue Sea." Justin Timberlake's wife was wearing a maternity denim overall that speaks comfort all the way, while not compromising style.

"Jessica Biel is winning the maternity fashion game as she continues to rock trends that boast comfort and style," said Us Weekly.

"Biel dressed her baby bump in the cool dark-washed one-piece with a blue winter coat, a white T-shirt, and blue sneakers," it said.

Rachel Bilson, Blake Lively and Isla Fisher are just among the celebrities who didn't compromise their fashion sense just because they got pregnant and were sporting baby bump.

The magazine noted how Rachel Bilson "looked chic at nine months pregnant in a loose pair with dark sunglasses and gray flip-flop sandals" before she gave birth to her first baby with boyfriend Hayden Christensen in October 2014.

Meanwhile, Justin Timberlake greeted his pregnant wife Jessica Biel a happy birthday through an Instagram post.

He wrote: "Happy Bday to the sweetest, most GORGEOUS, goofiest, most BAD-ASS chick I know. You make me smile 'til it hurts. I love you like crazy! --Your Huz."

"Jess' other baby, her beloved dog Tina, gave mama some lovin', too! The actress posted a picture to WhoSay of their 'Birthday smooch,' adding, 'Thanks everyone for all the good wishes!" reported E! News.

Birthdays are such a big deal in the Timberlake household. It was during the crooner's birthday in fact when he confirmed all the baby bump rumors surrounding Jessica Biel.

"Thank you EVERYONE for the Bday wishes!" he wrote. "This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets."

Justin Timberlake also posted a photo of him kissing pregnant Jessica Biel's baby bump.
