Sophie Monk's "Spice Up Your Life" PETA Ad

Sophie Monk, an Australian pop singer and actress, stripped off her clothes to promote the veggie diet.

The American Beauty inspired print and billboard campaign sports the tagline: “Spice Up Your Life—Go Vegetarian” and showed Sophie lying on a bed of red hot chili peppers.

According to PETA, Sophie wants fans to know that giving up meat is one of the best things you can do to "spice up your life." Eating a diet of vegetarian foods will give you more energy, help you stay trim, and improve blood flow to all of your body's organs.

"If you are going to take your clothes off for something, it better be a good cause," says Sophie in her interview for PETA.
