Don’t know about you guys, but Barbie dolls aren’t exactly the first thing that comes to mind when I think of the Sports Illustrated Swimsuit Issue. For some reason though, the company held a big event to celebrate SI‘s 50th anniversary issue. And I can’t really complain considering they invited hotties like Irina Shayk to show up and show off her perfect booty. Now when do we get to undress her? …What? That was always my favorite part about playing with my sister’s Barbies growing up.
