Before Pamela Anderson was in the spotlight and had the status as a sex symbol, she confessed she was "painfully shy."

The 55-year-old model admitted it was not until she first posed for Playboy in 1989 that she felt confident to be in her own skin.

"The shyness was something that was so debilitating. When I was little, I would wear a hat over my head and pull the hole closed so I could only see out this much," Anderson told ET Canada during an interview.

"I hated the way I looked, I hated everything. I was so shy, and I always thought everybody was pretty, and I just didn’t have that confidence or self-confidence."

"[I] thought ‘Why not? Let me try this.’ Then I got to L.A. and I was horrified," Anderson continued. 

Despite being overwhelmed and "scared," the 55-year-old model described how she shook off the nervous feeling and owned her first Playboy photo shoot.

"… I did my first photo shoot with Playboy… it was the first flash when I opened my eyes, and it felt like I was falling off a cliff. It really felt like I was just… allowing, instead of trying to control. And it was my first feeling of freedom," she told the media outlet.

In January, Anderson spoke candidly about her status as a sex symbol and revealed she never understood the conversation surrounding her appearance.

"I never felt like I was any kind of great beauty, ever, no. Just a little funny-looking," she said on the "Armchair Expert" podcast with Dax Shepard.

"I can’t wait to see myself old. I always said I’d recognize myself when I was old in the mirror," Anderson told Shepard on her plans to age naturally. "I want to let my hair go kind of natural gray, put my little straw hat on, don’t wear makeup. I mean, that’s my comfortable kind of state."
