Jessica Biel Blames Justin Timberlake For Her "Smile Lines" in a Sweet Birthday Post

Jessica Biel may have fallen asleep during Justin Timberlake's prebirthday celebrations, but don't worry — she made up for it on his actual 38th birthday by sharing a heartfelt shout-out on Instagram. On Jan. 31, Jessica posted a funny throwback photo of her and Justin underwater in their bathing suits and paired it with an oh-so-sweet caption.

"Since the days of embarrassing pink ruffled bikinis and underwater photo shoots, you have been infusing my life with so much joy and laughter that I blame YOU for my smile lines. But I wouldn't trade them for the world," Jessica wrote. She continued, "I wear them with pride knowing that I am the luckiest human around to have the honor of hearing your jokes, your words, your voice, every day of my life." Lucky is right! The 36-year-old actress finished the message by wishing a happy birthday to the "man of [her] blue ocean dreams," as a punny nod to the bright blue water in their photo.
