Jessica Biel says she is "the luckiest human" to be married to Justin Timberlake.
The 36-year-old actress - who has three-year-old son Silas with the 'Suits & Tie' hitmaker - marked her spouse's 38th birthday by posting a throwback picture of the couple underwater on Instagram, and admitted she doesn't mind having "smile lines", which she quipped are caused by her husband's jokes, because he fills her with so much "joy and laughter".
Alongside the snap, she wrote: "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. I wear them with pride knowing that I am the luckiest human around to have the honour of hearing your jokes, your words, your voice, ever day of my life. (sic)"
