Brooks Nader Says She Hopes to Be a 'Role Model' for Her 3 Younger Sisters (Exclusive)

Brooks Nader is all about sisterhood!

The model, 26, chatted exclusively with PEOPLE while attending the Club SI party in Las Vegas during the F1 Grand Prix Race, where she said she wants to serve as an inspiration for her younger sisters after appearing on the cover of Sports Illustrated Swimsuit earlier this year.

"I'm trying to be a role model to them, they're all models as well, so I gave them a little something to put on their wishlist," she said.

Scoring the cover of the iconic Sports Illustrated Swimsuit cover, Nader said, is something she thinks sisters Mary Holland, Grace Ann and Sarah Jane all have a chance to obtain someday as well.

“I think they can achieve it,” she told PEOPLE. "Anything's possible."

"I'm an example of that because I was told no by so many different people to this exact, very thing," Nader continued. "So anything's possible. Just hard work, [have] dedication and pursue your dreams.”

As for what inspires her to work hard for her goals, Nader said, "I wanted to prove people wrong."

“I also felt like I had a duty to younger girls in Louisiana, in my hometown, who look up to me or my younger sisters," she continued.

Added Nader: "I had a duty to show them that I am not going to take no for an answer, and I'm going to keep going. So that's kind of how I look at it.”
