Pamela Anderson is launching a pop career with her debut single, “High.” It’s not about drugs, but about high fashion, her friend Richie Rich says. “We are recording a pop single together. Pam says she wants to sing, but nothing too difficult, so she’s just going to sing the word ‘high’ over and over,” he told us. He and Anderson are also launching a new clothing line, A*Muse, which she’ll model during Fashion Week in February, while her supportive ex, Tommy Lee, spins records.
