We know Yolanda Hadid must have done something right considering she has two majorly successful daughters in the modeling world, but she never let her girls walk a runway until they were 18.

According to Us Magazine, Yolanda says “I never let them work as models before they were 18… I didn’t want anybody judging them on what they looked like. I wanted them to feel and be the authentic human beings that they are, and I think that created a lot of strength for them.”

Obviously if you’ve seen Bella and Gigi, you know they didn’t have anything to worry about in the looks department, but it’s nice that Yolanda had the wherewithal to raise them right.

Especially growing up in the Beverly Hills area, they could have dived into modeling much earlier. Yolonda preaches humility though… She tells Us Magazine, “I always said to them, ‘Listen, there are thousands of girls that are much more beautiful than you girls, but you have an extraordinary character and you’re going to have to set yourself apart by being a role model, by showing up and being kind to everybody.”

No wonder Gigi and Bella are killing it in all departments.
