Pamela Anderson cried during first Playboy shoot

Anderson was stunned when the adult publication asked her to bare all for them, the Contactmusic reported.

"I was so confused. I told my mom about the offer and she said, 'Do it. I'd do it'. I was so shy I was sick. They got the cover in the first roll of film because I was in tears... And then, after a while shooting, I became so comfortable they had to stop before I walked out of the studio door nude," Anderson said.

The 43-year-old Hollywood star first appeared as Playboy cover girl in 1989 and was selected as their Playmate of the Month in 1990.

Since then Anderson has appeared for a record 13th time on the magazine's 57-year publishing history, most recently for their January issue.

The former 'Baywatch' star also regret going under the knife to enhance her appearance and has vowed to age gracefully.
