Hayden Panettiere, is the February cover star of Lucky Magazine.

As People Magazine confirmed, the 18-year-old actress is currently dating her 30-year-old Heroes co-star, Milo Ventimiglia. She told Lucky that she is transitioning into a more glamorous look as she gets older.

“Right now my style is very frenetic,” says Hayden Panettiere. “It seriously changes as quickly as my mood.” The petite 18-year-old, who stars are the (literally) invincible cheerleader on the NBC hit Heroes—and will be seen later this year alongside Julia Roberts in the drama Fireflies in the Garden—arrived at our L.A. Photo shoot and immediately made a beeline for the shoes. Before she’d even gone to hair and makeup, Panettiere had tried on every single pair we’d brought—quite an accomplishment. “I’m kind of obsessive about really stunning heels,” she says. “I get excited even taking the elevator up to the shoe floor at Bergdorf’s.”

Hayden Panettiere is at a point in her life when she’s transitioning from jeans-and-flip-flops teenager to glamorous Hollywood actress. “I’ve only recently been able to try out a bunch of different styles without feeling like I’m dressing beyond my age,” says the Heroes star. “On the show, I spend most of my time in a cheerleading uniform, so in real life I like to have a lot more fun with my clothes.”
