Hayden and Masi Milk It

Thu., Aug. 23, 2007 12:16 PM PDT by Sarah Hall

The dairy industry has a new set of heroes.

Hayden Panettiere and Masi Oka have signed on as the latest subjects of the white-mustachioed Got Milk? ads, as part of the Body by Milk campaign created to encourage teens to down one to three glasses of the bone-building beverage every day.

Both Heroes stars make their milk-pushing debut next month—Panettiere in the October issue of Alloy magazine and Oka in Marvel Comics on Sept. 1.

For her ad, the barely legal Panettiere wears a skintight red dress and clutches an exploding glass of milk. Her tagline reads, in part, "You don't have to be a hero to feel invincible," a nod to her character Claire Bennett's ability to spontaneously heal herself.

Oka wears a shirt and tie in his ad, and appears windblown, as if he's just returning from a time traveling experience à la his character, Hiro Nakamura. His copy reads, in part, "My hero? Think hard. It's milk…So grab a glass. Then you can change the future too."

Other celebrities starring in the Body campaign include the casts of Fantastic Four: Rise of the Silver Surfer and High School Musical 2.

While Panettiere and Oka are relying on milk to do their bodies good, their costar Ali Larter is embracing her natural beauty.

The actress has signed on as spokesmodel for Dove's Real Beauty campaign, vowing to forgo the hours of styling her counterparts will undergo before the 59th Annual Emmy Awards in favor of creating her own red carpet hairdo.

"There is a lot of work that goes into Hollywood hair, and I want women to know that it is unrealistic for every day," Larter said in a statement. "I am going to go out on a limb by doing my own hair for the Emmys without any stylists.

"I am going to use Dove Hair Care products for five days, get my hair in great shape, and I am going to rock the red carpet. I am doing all of this to help women realize the potential of their own hair and feel more confident every day."

In conjunction with Larter's participation in the Real Beauty campaign, Dove Hair Care will make a donation to send girls from across the U.S. to self-esteem workshops through Uniquely ME!, the Girl Scout-Dove Self-Esteem Fund program.

With the second season of Heroes set to premiere on NBC Sept. 24 and the season one DVD coming out on Tuesday, the cast of the show is embarking on a promotional global road trip.

Panettiere will be dispatched to Europe Sunday, along with Jack Coleman Adrian Pasdar, Milo Ventimiglia and executive producer Dennis Hammer, where they'll preach the Heroes gospel in Munich, Paris and London.

Oka and Larter will head up the Asian leg of the tour, visiting Tokyo, Hong Kong and Singapore along with Greg Grunberg and Sendhil Ramamurthy.

Remaining castmembers Noah Grey-Cabey, James Kyson Lee, Zachary Quinto and newcomer Dania Ramirez, accompanied by coexecutive producer Jeph Loeb and graphic-novel artist Tim Sale, will be sticking closer to home with promo stops in New York City and Toronto.
