Justin Timberlake and Jessica Biel are a fairly private couple who don't spend too much time posing on red carpets together, but the duo couldn't seem to get enough of one another this week at the Cannes Film Festival.

Jessica is in town supporting her husband while he promotes his new film Inside Llewyn Davis, and on Monday, she couldn't stop smiling as she accompanied him to the Chanal Plus event. Looks like married life is really working wonders for this hot couple!

Adding to their natural glow, of course, was the couple's impeccable style, with Jessica turning heads in a black-and-white Roksanda Illincic gown with orange sleeves and Justin looking dapper but a bit more low-key in an unbuttoned gray suit jacket and black pants. (Suit? Check. Tie? MIA.) Seemingly without trying, the sexy duo manages to compliment one another perfectly for their walk through Cannes. During the event, Justin answered questions on stage, with Jessica proudly looking on in the background.

The film premiered the night before, and Jessica was on-hand then, too, standing by her man on the red carpet and posing for photos, while once again stealing the show in a Marchesa number.

Since these two got married last fall, Jessica has kind of put her career on hold, not taking on too much work as a newlywed. On the other hand, Justin worked hard to produce a new album, The 20/20 Experience, released in two parts, the second of which we won't hear until September. Additionally, he'll be heading out on a world tour beginning in the fall, so that'll definitely keep the couple busy if Jessica decides to join him.

Hmm... starting a family will have to be put on the back burner for a bit, huh?
