Pam Anderson: Mystery Guest Flashes Her Breasts

The blond pinup accidentally shows of her bosom during a taping of new variety show

Pamela Anderson has no problem getting naked in public. But sometimes it's not even intentional!

The buxom blonde accidentally flashed her breasts to an entire studio audience during a taping yesterday of Osbournes: Reloaded, a new upcoming variety show hosted by Sharon, Ozzy, Kelly and Jack Osbourne.

Anderson's breast boo-boo happened during a skit called "Guess the Guest," according to an eyewitness.

"The Osbournes blindfold themselves and ask the guest questions to guess who they are," my source says. "Pam was sprawled on the stage, but when she got up, the top half of her dress completely flopped forward exposing everything."

The Osbournes never actually saw what happened because they remained blindfolded. "They heard it all and were very confused," the source says. "It was very funny."

Will the blooper make it on air? Looks like it, because they did not do a redo.

A rep for the show insists none of Anderson's naughty bits were actually exposed.

"I know that Pam had some issues wit the zipper on the back of her dress," the rep says. "But as far as I saw, she remained properly covered and nothing was revealed to the audience."

Airdates for the new show have not been announced.
