Yesterday, Jessica turned 33 years old and in a rare post about his other half, Justin showered her with affection with a sweet birthday message.
Taking to Instagram, the 'Suit & Tie' singer shared a loved-up photo of himself and his wife. While Jessica is pictured sitting down and smiling, Justin is stood over her looking down lovingly at the Hitchcock star.
Alongside his photo, he said: "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."
How cute is that?!
Justin and Jessica first began dating eight years ago and went on to marry in Italy in October 2012.
The couple are now expecting their first baby together.
Reports of Jessica's pregnancy surfaced in November last year, with her and Justin keeping quiet on their baby news at first.
Finally confirming the rumours they were set to be parents, Justin shared a picture of Jessica's baby bump with fans last month on his birthday.
In the photo, Justin can be seen planting a kiss on his wife's growing tum. Next to his Instagram post, 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,."
Justin's N'Sync bandmates have already sent their congratulations to the star.
While Joey Fatone said he thinks the couple will have a lot of "fun" looking after their little one, Lance Bass recently told Reveal Justin and Jessica will make "amazing" parents.
"I'm so excited for the both of them," he told us. "[Justin and Jessica] are going to be amazing parents. I can't wait to be a new guncle - gay uncle!"
