The 30-year-old model and 37-year-old singer took a family portrait with 2-month-old daughter Luna while spending time with Teigen's mom, Vilailuck Teigen, on Sunday.
Vilailuck shared the family photo Monday on Instagram and captioned the picture with family and heart emojis. Legend also posted a snapshot of Teigen and Luna from the same outing, writing, "Sunday with my ladies."
Teigen and Legend started dating in 2007 and married in Como, Italy, in September 2013. The couple welcomed Luna in April and have been enjoying the "exciting" experience of first-time parenthood since.
"We're so happy," Teigen told Entertainment Tonight in May. "It's been really exciting and fun, and every day is so different, and seeing all her little changes is so cute."
"It's the little smiles that get you," she added. "There is no feeling like that first little smile, your first Mother's Day, which was so beautiful and sweet to me. The entire day my eyes were on the verge of tears because I was so happy."
Legend defended Teigen from mom-shamers the same month after the model faced backlash for going on a date night. Teigen hosts Spike series Lip Sync Battle, while Legend last released Love in the Future in 2013.
