Gigi Hadid and Bella Hadid have had quite a year.

Walking Rihanna's Fenty x Puma runway show, appearing in sexy music videos and on billboards, gracing runways and covers of magazines, dating famous guys and boasting Instagram followings in the millions: This is just a typical month for Gigi and Bella, whose respective rises to the top have been swift. While Gigi closed Rihanna's show and starred in boyfriend Zayn Malik's latest video, her fellow It girl Bella is also covering magazines and walking runways galore, and just last night she accompanied her boyfriend, The Weeknd, to the Grammys.

With so much excitement all the time and so many accomplishments under their belts, how do the stunning sisters stay humble and down to earth?

Well, that's where Gigi and Bella Hadid's mama bear, Yolanda Foster, comes in. The mother of three took a break from the chaos of New York Fashion Week to speak to E! New about how she keeps her famous girls from losing themselves to the limelight.

"At the end of the day, both Gigi and Bella are simple girls that were raised on a farm in Santa Barbara, riding horses every day of their lives," the Real Housewives of Beverly Hills star confided to us.

"This is all great and beautiful," Foster added, referring to the chaotic modeling scene around her, "but this is business, this is work. I can see when this all becomes too much, I put them on a horse, let them jump a couple of courses, and that's when they get back to, 'OK, I remember, this is who I am.'"

When asked about her health and continued fight with Lyme disease, Foster replied, "You know, I'm up, out of bed, and you know, excited to be here."

The Dutch beauty certainly looked fresher and healthier than she has in a while

Meanwhile, 20-year-old old Gigi has teamed up with Tommy Hilfiger to create a Gigi for Tommy Hilfiger collection.

"With her Southern California style, she has a cool, casual look that is beyond," the designer gushed when asked about his collaboration with Hadid. "She has her feet on the ground, and beauty to match."

Tip of the hat to Mom on that one.
