The couple also had their seven-year-old daughter Luna Legend with them as they shopped at Gigi Hadid's, 28, Guest In Residence pop-up shop in New York City.

Luna looked adorable in a pink and white checkered jacket and skirt with a white t-shirt underneath the jacket and pink combat style boots on her feet.

Their busy evening continued and the couple were later seen leaving the renowned Japanese restaurant BONDST after a romantic dinner.

The loved-up couple held hands as they walked down the stairs together.

The outing came after the couple enjoyed an evening away from their children on Thursday evening, having spent the afternoon playing with drones in Washington Square Park with their two eldest children, Luna and Miles, five.

As the family stepped out to celebrate the superstar turning another year older, John appeared to be having a blast with his little ones, who were bundled up in padded black jackets and hats.

Teigen was every bit the doting wife as she stayed by her husband's side and walked arm in arm with him down the sidewalk toward the public park in Lower Manhattan.

In addition to Wren, who was born on June 19, the couple has another daughter, Esti, 11 months old.

Chrissy and John met on the set of his music video for Stereo in 2006, got engaged in 2011 and married in 2013.

In 2014, she described to Wendy Williams the day they met (via USA Today).
