Mary Carey Tries on Birthday Suit

Britney may have broadcast her bits all over Hollywood a few times, but Mary Carey takes the cake!

TMZ filmed porn star Mary Carey while she shopped at Beverly Hills Pimps & Ho's (make your own joke here), and while picking out a dress, she stripped bare to try it on -- right in the middle of the store! Let's just say our cameraman had a great day at work ... take a look at the tape and you will too!

The former candidate for Governor of California and "Funbag Fantasies 5" star is clearly preparing a new platform for her next run for office.
