Justin Timberlake's wife shares rare family photo with their child

Jessica Biel, known for her roles in "The Illusionist" and "I Now Pronounce You Chuck & Larry," shared an adorable photo online.

Biel was in the Netherlands to support husband Justin Timberlake on his tour, and the couple was photographed walking on the beach with their son.

She wrote in the caption: "Do we look European? Because we sure feel European! Summer please never end."

Biel also thanked the MOTW tour "for such an incredible adventure. She tagged Justin Timberlake and his band, The Tennessee Kids, in the post.

Biel could be seen wearing a white sweater and denim shorts, while their son, Silas, was dressed in a green hoodie and sweatpants.

Timberlake wore a light blue hoodie and sweatpants as well, and all three enjoyed the stroll barefoot.

The proud father and family man also shared photos with his 51 million Instagram followers, and in one of the snapshots captioned "Midnight," he kisses Biel.

The Eifel tower can be seen in the background, and Timberlake referred to Paris as the "The City of Love" in a post dedicated to his wife and son.

When asked what the secret to their strong marriage was, Biel said they are lucky enough to "stay in different places and live in different places while [they] work."

That doesn't mean the duo doesn't work at their marriage: Biel explained that couples "really [...] have to work hard."

She added: "That doesn’t change if you work at home or in an office or you’re on tour. It doesn’t change; the work doesn’t change."

They met back in 2007 and Timberlake popped the big question four years later. They exchanged vows in 2012 and welcomed Silas in 2015.
