This bouncy Belgian beautyย knows how to bikini with the best of them.

Rose Bertram is, clearly, a smoking hot model who, like the last several of our Babes of the Day, also appeared in the Sports Illustrated Swimsuit Issue. Did you guys know how many hot chicks were taking pictures for this magazine? When were you going to tell us? They have, like, all of the babes. What have we been doing with our lives before now? Why are we asking so many questions and not looking at Rose's "Bertrams," which are prominently on display in the pics and video below?
