The Hot in Cleveland star poses with shirtless, hunky men in a calendar to raise money for her fave charity, Morris Animal Foundation. The group, of which White is a trustee, helps promote health and welfare research for animals and wildlife worldwide.

The $12.99 calendar hits stores this September; it features a mix of new and archived photos of the star.

White has been in the midst of a career resurgence since appearing in a hilarious Snickers ad that aired during the Super Bowl. Her sitcom, Hot in Cleveland, was renewed for a second season after just one month on the air, and her Saturday Night Live appearance in May was one of the highest-rated episodes of the season.
