Dad isn't her only admirer. Since she began designing the edgy blouses, frocks and gowns she describes as "girly with an S&M feel," Jennifer, 40, has won a host of enthusiasts, including Nicky Hilton, Jennifer Tilly and Lisa Rinna. Nicholson's upbringing helped. As a girl, she was inspired by the distinct style of her father's girlfriends, Anjelica Houston and Michelle Phillips among them. And when she visited Dad (who was divorced from her mom, actress Sandra Knight, in 1967), "we did a lot of shopping," Nicholson recalls.
Always artistic, she tried acting before taking up design in 1999; she opened a boutique, Mlle. Pearl, in Santa Monica in 2001. Divorced from the father of her two sons (Sean, 7, and Duke, 4), Nicholson is thrilled to have found her niche. "I'm doing my own thing that has nothing to do with my father," she says. He does, however, intend to benefit. "I'll do my Christmas shopping at her store," Jack says. "I just hope I can persuade her to give me a little discount."
