It was the best of times, it was the worst of times. After this morning's news that Eva Mendes entered rehab, Calvin Klein Inc. announced that she will be the face of a new perfume expected to be released this fall. Details of the new fragrance are minimal at this point, but it will be the newest Calvin fragrance since he launched Man last fall. As for Eva, the Calvin collaboration follows her stint as a spokesperson for Revlon. Here's to hoping this campaign won't be nearly as creepy as some of Calvin's older advertisements.
