Katelyn Tarver shows off her pearly whites as she stops by the K-Swiss Party to launch the Vintage California Collection held at Kitson in Malibu, Calif., late last week.

The 20-year-old actress/singer was joined at the event by Nick channel-mate Robbie Amell. The Vintage California began as a prototype, designed in the 1960s, and served as the predecessor to the infamous K-Swiss Classic. The style first debuted in the mid 1980s and is making a rare comeback this Spring.

Katelyn also just uploaded some super-cute behind the scenes pics from Big Time Rush on her MySpace.
