Lindsay Lohan and Nicole Richie channel Lady GaGa for their forays into fashion.

Nicole - who is expecting her second child with partner Joel Madden - steals the Just Dance star's glam punk rock look in a special music issue of US magazine BlackBook.

Meanwhile, Lindsay goes GaGa in a new TV commercial for Italian fashion label Fornarina.

Wearing the singer's trademark bleached blonde wig with severe fringe and thigh-high pvc-look boots, the hard-up actress parades in front of a neon background.

Lindsay strikes a shooting pose with her hand and blows a kiss as she says: "Bang. Wink. Smack." in a 80s-inspired clip.

Fornarina spokesman has said of Lindsay: "She is that very self-confident, dynamic woman.

"She's got a lot of attitude. That's what we're hoping our customer will aspire to."

Lady GaGa herself must have had other commitments.
