Pamela Anderson's role as a lifeguard on Baywatch made her a global sex symbol in the '90s. But she longed to be taken seriously as a performer and person. "I've always been carrying this secret. I feel like I've known I was capable of more, but I didn't know what," she says. She now stars in The Last Showgirl. She spoke with Tonya Mosley about her career comeback, crafting her persona, and ditching makeup.
