Justin Timberlake wished "[his] heart" Jessica Biel a very happy birthday on Friday.

On March 3, the Oscar-nominated singer-songwriter shared a sweet kiss selfie of himself and his wife on Instagram, where he also wrote a romantic message for the actress in celebration of her 35th birthday.

"You make me laugh. You make me smile. You make me LOVE. You make me want to be BETTER. Speaking of, it doesn't get any BETTER than you," Timberlake shared.

"Now, I know for sure that it's BETTER to be lucky than good. Ask me who the luckiest guy in the world is and I will tell you that you are looking at him. Happy Birthday, my heart," he concluded, signing his note with "J".
