Celebrate Kate Upton's birthday with 23 of her hottest SI Swimsuit shots!

Kelsey Hendrix | Jun 8, 2015

Once a year, we get to thank the forces in the universe that brought us America's favorite bombshell and two-time SI Swimsuit cover model Kate Upton. Today is that day.

Join us in wishing the 23-year-old Michigan native the happiest of birthdays!

Best known here at SI Swimsuit for her sexy back-to-back covers in 2012 and 2013, as well as her gorgeous flip cover for our 50th anniversary issue, Kate is what you might call an SI Swimsuit role model. Rookies want to be her, current models love her, and alums respect her.

So it's only natural that when Kate has an occasion to celebrate, so do we! From her recent PSA about the true appeal of granny panties to her unforgettable intimates reel from Antarctica, we've got about 100+ reasons to show our appreciation for the fact that Kate Upton was born.

Take a moment to wish Kate a happy birthday and bask in her first 23 years of beauty. We certainly can't wait for the next 23—happy birthday, Kate!
