When it comes to her lip-smacking beauty secret, Petra Nemcova's lips aren't sealed.
The supermodel-turned-activist cops to being obsessed with Clinique's Chubby Stick moisturizing lip color balm, which comes in 16 lush shades.
And it's those sumptuous colors—which range from muted ("Heaping Hazelnut") to eye-popping ("Chunky Cherry")—that have her hooked, she says.
"They have many different colors, and they are brilliant," the 33-year-old Czech beauty told us recently backstage at the Hervé Léger show at New York Fashion Week.
The lip balms, she raves, are a hit with her because they're "very playful, and they have the new line, Intense, which [has] even more deeper color."
She also adds that the product, which retails for $16 a pop, is "an affordable way to be playful and fashionable."
Playful and fashionable: We're betting the statuesque stunner knows a thing two about that.
