Justin Timberlake took to Instagram on Tuesday to share a sweet birthday message for his pregnant wife, Jessica Biel, who turns 33 on March 3. He posted a smiley photo with the caption "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." The snap comes just weeks after Justin shared another photo that showed him kissing Jessica's baby belly for his own birthday in January. It was the first time that Justin publicly commented on the baby news, and now it looks like the couple is having some fun with it since Jessica playfully posed with her head on Justin's stomach.
