As we reported yesterday, Nicollette Sheridan and her boyfriend Michael Bolton enjoyed some holiday down time on the beach in St. Barts.

While Nicollette frolicked in the waves, it seems she had a bit of a mishap with her bikini top and provided us with what might just be the last nip slip of the 2007.
