Workout buddies! Jessica Biel and Justin Timberlake broke a sweat together while hiking in New Zealand on Wednesday, Oct. 15. Today, Oct. 19, they celebrate their two-year wedding anniversary.

The "Mirrors" singer led the way down a small hill as the couple were joined by other friends. He donned an all grey outfit, including a long-sleeve shirt, matching T-shirt, and baseball cap. Biel, 32, kept close behind in tight workout pants and a loose-fitted top. She wore a colorful hat and tied a grey sweatshirt around her waist.

That same day, Timberlake, 33, shared a rare intimate picture of the husband and wife staring out at the gorgeous coastline around Auckland, New Zealand. The snapshot, in fact, is the first Instagram picture the singer has ever shared of Biel, whom he married in Italy in 2012.

"Life moves pretty fast. If you don't stop and look around once in a while, you could miss it," he captioned the pic, referencing the famous line from 1986's Ferris Bueller's Day Off.

The lovebirds have spent some time apart in the past few months as Timberlake has been traveling for his 20/20 Experience world tour.
