On Wednesday, March 18, Justin Timberlake and Jessica Biel went to the grand opening of Hollywood's Greenleaf Gourmet Chopshop. The couple didn't want to miss a chance to spend their final night out together before they become parents.

The soon-to-be first-time parents seemed to enjoy being at a restaurant together as Biel is fastly approaching her due date. A source told E! News, "She is close (to giving birth). She was drinking water and staying hydrated and was very, very pleasant with everyone. Super sweet and charming." The insider added that Biel and Timberlake "stayed together the whole night. He was very protective of her in that way. It was really nice to have them here."

34-year-old Timberlake and 32-year-old Biel walked down the aisle October 2012 in southern Italy. Timberlake said two years ago on "The Ellen DeGeneres Show" that his decision to marry Biel was the best decision he ever made. "Every once in a while I can catch a glimpse of her when she doesn't see me looking, and I have this moment where I'm like, 'If you never make a good decision...if you only make bad decisions for the rest of your life. You made one really good decision,' " Timberlake said to a swooning crowd, continuing, "Because she's just like...it's nice to marry your friend. It's nice to marry your best friend. It suits me."

Just three weeks ago, Timberlake wished his wife a happy birthday on his Instagram account. 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!"

So far, the gender of their baby is still unknown as they opted not to find it out before the baby's born.
