Seriously, who's that girl? Nope, it's not Madonna. It's Cameron. Cameron Diaz.

The surfer girl goes Material Girl -- cone-shaped bra and all -- for the August issue of V Magazine, and we've got the pictures to prove it.

According to V, Diaz recognizes that it's time to switch gears -- to dig deeper for her roles. "I'm not going to be the 23-year-old ingenue again," she told the magazine. "If I tried to hold on to that, I'd be a pretty unhappy individual."

Diaz has already begun the transformation by taking on portraying the mother of a terminally ill child in "My Sister's Keeper," as well as the upcoming October horror film "The Box," by "Donnie Darko" director Richard Kelly.

Playing a mother didn't seem to answer the nagging question, or rather, Hollywood's nagging question on impending motherhood. "I don't declare either way if I'm going to have children," she says. "I don't know what will happen...and I'm totally fine with that."

For now, though, Diaz is content working on herself and renovating her West Coast home. The actress remains open to playing a variety of roles, as seen here in her Madonna-circa-1987 photographs.

The August issue of V Magazine is hits stands July 7.

    Photographer Steven Meisel used a technique called "solarization," favored by the legendary Man Ray, to achieve a techno-rainbow exposure.

    Marc Jacobs says there is a unity to the campaigns "it feels like we have completed both parts of the story." (Referring to Madonna's last turn as the face of Louis Vuitton.)

    The lush, colorful clothing was inspired by Tamara de Lempicka artwork.

    This is the face of a 50-year-old. Amazing. The purse is not too shabby either.
