In November last year, reports first emerged that Jessica was pregnant with her and Justin's first child. Although, the pair only recently came clean about their baby joy.
And now their news is out there, Jessica is finally showing off her blossoming baby bump.
Sharing her first post in two months on Instagram, Jessica treated fans to a glimpse of her growing tum in her latest snap.
In the photo, the A-Team star looks gorgeous, rocking jeans, a white blazer and a loose-fitted top.
Ditching her skyscraper heels, Jessica treated her feet to a cute pair of low-heeled courts instead, finishing her ensemble with a cool pair of shades.
The star and her bump were joined by two of Jessica's friends as she celebrated her new venture Au Fudge - a child-friendly restaurant she is set to launch in Santa Monica.
Jessica's latest photo comes after Justin recently confirmed he and his wife are expecting a baby together.
After months of speculation, the 'Mirrors' singer finally came clean about his wife's pregnancy. Taking to Instagram on his birthday, Justin shared a very cute snap of him kissing Jessica's bare baby bump.
Alongside his photo, he said: "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets."
Despite only just confirming they have a little one on the way, Jessica's HUGE baby bump suggests she and Justin won't have very long to go until they meet their bubba.
