Legend's sweet bond with Luna, played a part in Teigen choosing to have a daughter. The couple conceived through in vitro fertilization, and as Teigen explained to People last year, she knew that her husband would be "the best father to a little girl."
"I picked the girl from her little embryo," Teigen recalled. "I picked her and was like, 'Let's put in the girl.'"
"I think I was most excited and allured by the fact that John would be the best father to a little girl. That excited me," she explained. "It excited me to see … just the thought of seeing him with a little girl. I think he deserves a little girl. I think he deserves that bond."
