In an Instagram video she posted on Tuesday, Teigen, 31, introduced her 11-month-old daughter to a bunny while holding the little girl in her arms. Luna stroked the bunny’s black and brown fur, as her mother encouraged her to look at the furry animal.
“It was fun. We invited a lot of our friends with kids over, and it was for no particular reason other than Chrissy wanted a petting zoo,” Teigen’s husband John Legend told PEOPLE Tuesday night at The Most Powerful Stylists in Hollywood event, hosted by The Hollywood Reporter and Jimmy Choo.
“It was nobody’s birthday, it was just for fun, and we had so much fun,” Legend adds.

Teigen also spent some quality one-on-one time with the critters, sitting in the middle of their pen as she cuddled with a baby pig and laughed, saying, “This is so great!”
“It was fun putting Luna on the little pony and have her ride around,” he continues. “Honestly, she probably doesn’t know enough to be afraid, so she’s like, ‘Eh, f— it.’ ”
“We were always different,” Legend says. “I was always a little bit more buttoned-up, and she was always more brash and free.”
“I would get a little nervous at first with some of the things she would say, because I didn’t know how people would react,” the La La Land star admits. “I usually played it more safely.”

But Teigen’s bold, infectious spirit quickly had him head over heels, and changed him for the better.
“I think she’s brought me out of my shell a bit, and made me enjoy life a little bit more,” Legend adds. “It’s been fun to grow together in that.”
