Palmer has already stripped down for the cameras and it won’t be long before we see the results, as she is set to appear on the cover of Playboy’s March issue, which is scheduled to hit newsstands next month.

And with Sports Illustrated having announced on Monday that Kate Upton will be appearing on the cover of their 2012 Swimsuit Issue, we can’t help but wonder who the sexier cover girl is.
