Cassie

Sexy R&B singer Cassie has stripped down for a sexy new photo-spread in women's magazine Allure.

Cassie joins actress Marley Shelton, Kristin Chenoweth, Carla Gugino, and 'Ugly Betty' star Vanessa Williams for the special issue titled 'What Lies Beneath.’

While Shelton admitted that she was only comfortable after Gugino posed nude first, sitting on a tree trunk, the latter revealed that her boyfriend is already excited about the photospread.

"He wrote back, 'I'm hyperventilating," Contactmusic quoted Gugino, as saying.

The bare-all photospread appears in the magazine's May issue.
