Erin Heatherton may be a SI Swimsuit rookie, but it's already unusual to come to Swim Daily and not see her face at the top of our page.

From participating in the first-ever Fitbit Celebrity Challenge (against SI Swimsuit alum Hilary Rhoda), to helping SI and MLB player Giancarlo Stanton with our premiere body-paint cover, our girl is quite simply everywhere! And we couldn't be happier about it.

So on the most special of days—Erin turns 26 years old today!—we wanted to send our love to one stellar rookie. Not only do your blonde curls, flawless figure and playful freckles mesmerize us, but so does your outstanding personality.

We're lucky to call you one of our own, Erin Heatherton, and we're wishing you the happiest of birthdays!
