Hailey Clauson is taking over!

For the first time in its 52-year history, Sports Illustrated chose three cover models for their iconic Swimsuit Issue.

So what's her story? Keep reading to learn more about the 20-year-old beauty.

1. SI isn't the only magazine cover you've seen her on.

Clauson is no stranger to being a cover girl. While her face appeared on plenty of glossy covers over the years, including Vogue Japan and Vogue Russia, she most recently landed the cover spots for Elle magazine's France, Spain and Russia editions.

The Thousand Oaks, California, native started modeling when she was 14 years old, appearing in ads for trendy brands like Wildfox Couture, Forever21, Gucci and Jill Stuart.

2. She's new to Snapchat, but wants you to follow her.

While she claims she "still don't know how to work it well," Clauson is all about the selfies and 10-second videos on Snapchat. If you want to give her an add, she goes by the username @haileyclauson.

Brace yourself for silly (but somehow still sexy!) snaps, like this one:

3. She's dating a fellow model.

Clauson's beau is just as good looking as she is! Jullien Herrera, a model, personal trainer and boxing instructor based in New York City, is the man she calls the "love" of her life, "best friend" and "most amazing boyfriend."

4. She loves junk food.

Don't let her petite figure fool you -- Clauson loves her comfort food! The model's Instagram is filled with posts of delicious treats, like Krispy Kreme donuts, Flaming Hot Cheetos, banana pudding from Magnolia Bakery and, of course, pizza.

Lots of pizza.

We're not kidding.

5. She's a dog lover.

The model calls herself "mom" to a pit bull named Mahala, whom she rescued.

Clauson is a big advocate for animals, frequently encouraging her followers who are looking for a pet to consider adopting from a shelter.

And it looks like Mahala is already following in his mom's modeling footsteps.

6. She credits her flawless physique to boxing.

Her hobbies include kicking it at the beach and boxing, a passion she shares with her boyfriend. Judging by the short clips and photos she's posted on social media, we definitely wouldn't want to mess with her.
