Paris Hilton is speaking out against drunk driving.
The December issue of Seventeen magazine features Hilton, 25, warning teens not to get behind the wheel if they’ve been drinking.
“All it takes is one drink to mess with the way you drive – it clouds your judgment and slows your reflexes," she says in the ad. "Don’t take any chances. It just isn’t worth it."
In the magazine's cover story, the heiress also says she hasn’t reached her sexual peak. “I think you like [sex] when you’re, like, in your thirties,” she says. “That’s what someone told me. We’ll see.”
