Justin Timberlake Instagrams First Pic With Jessica Biel--and They've Been Married Almost 2 Years!

Justin Timberlake and Jessica Biel aren't the type to flaunt their love on social media.

In fact, the "Not a Bad Thing" singer Instagrammed his first picture ever of his wife Monday--just six days before they'll celebrate their second wedding anniversary on Sunday.

In the rare, intimate shot of the twosome, Justin, 33, has his arm around Jessica, 32, as they sit on a park bench overlooking the water in New Zealand. Justin, whose wife has joined him for the Down Under leg of his 20/20 Experience world tour, shared a famous quote from the 1986 movie, Ferris Bueller's Day Off: "Life moves pretty fast. If you don't stop and look around once in a while, you could miss it."

Indeed, it does! It seems like only yesterday that J.T. and J.B. were saying "I do" at the Borgo Egnazia resort in Fasano, Italy, surrounded by their family and friends. Nearly two years have flown by since their Oct. 19, 2012 wedding--and from what we can surmise, they're loving every minute of it.

Mrs. Timberlake famously gushed to Ellen DeGeneres in November 2012 that the best thing about being married is getting to call the former 'N Sync frontman "my husband."

When Ellen asked Justin the same question a few months later, he joked, "Calling her my husband? No. I don't know, every once in a while I can catch a glimpse of her when she doesn't see me looking and I have this moment where I'm like--'if you never make a good decision...if you only make bad decisions for the rest of your life, you made one really good decision.'"

"It's nice," he added, adorably, "to marry your best friend."
