Justin Timberlake and Jessica Biel are one of the most notoriously low-key married celebrity couples, so it’s always cute when they proclaim their love for each other publicly.

On Biel’s 33rd birthday, Timberlake gushed about her in an Instagram post.

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

Biel is getting the gift of a lifetime this year, because the couple is expecting their first child. After months of rumors, Timberlake confirmed her pregnancy last month.

After thanking everyone for birthday wishes of his own, he gushed, “This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets.”

Biel is currently filming The Devil and the Deep Blue Sea in New Orleans. She’s due in April.
