New year, new model, same instant-star effect.
But it's easiest to compare Shayk to Brooklyn Decker, the model who graced SI's Swimsuit Issue last year. Below, a breakdown of how they stack up:
Age and background: Shayk, 25, hails from Yemanzhelinsk, Russia. Decker, 23, was born in Ohio and grew up in North Carolina.
Before the coveted SI cover: After winning a Russian beauty pageant in 2004, Shayk began pursuing a career in modeling. In 2007, she made her SI Swimsuit Issue debut inside the pages of the magazine and has appeared in every swimsuit edition since. She's also modeled for Lacoste, Guess, Armani Exchange and the lingerie brands Intimissimi and LaPerla.
Decker started modeling after being discovered at a shopping mall in Charlotte, N.C. as a teen. She first appeared in SI's swimsuit issue in 2006 and got more attention from the magazine in 2007 and 2008 before landing the 2010 cover. She also had a handful of acting gigs on TV shows including "Ugly Betty" and "Royal Pains."
