In the immortal words of Britney Spears (I never thought I would say that) "You gotta work bitch". With Sarah those words couldn't be truer. Someone who is always busting their ass at the gym and drinking green coloured shakes most of us couldn't be paid to drink. For Sarah not only did we get some great beach shots but we also wanted to show what it took to get there. We also wanted to give the Calvin Klein models a run for their money.
