Karina Smirnoff likes to push things to the limit: Aside from flying around the ballroom on Dancing with the Stars, she enjoys boxing, skydiving and shooting guns.

"I'm fearless and love the adrenaline rush," the dancing pro, 32, tells Playboy, underscoring the point by posing nude in the May issue.

Smirnoff, who this season is paired with leader Ralph Macchio, wears little more than a few red ribbons and a sultry stare as the first Dancing pro to strip down for the magazine.

"Sexy is the confident energy a person produces," she tells Playboy. "Sexy is the comfortable feeling of being who you are."
