"Let me tell y'all about this human… she is the most bad---, most graceful, most gorgeous DREAM of a partner I could have ever wished for," Timberlake wrote. "And today is her bday!"

"I'm so glad you were born, my love," he added. "And, I'm so lucky that you are choosing to do this thing called life with me. Aging like a FINE 🍷!!!!"

In a separate Instagram post shared on her page, Biel shared photos of her together with Timberlake. In them, she wears big sunglasses with a jewel in the center.

"Birthday vibes so bright I had to see it with my third eye," she said. "Thanks for all the lovely wishes!"
