Olesya grew up in the 12-house village of Likhoslavi (Stoplight population: 0) before emigrating to the U.S. when she was 8. She's starred in High School Musical, High School Musical 2, High School Musical 3, and was completely convincing playing American teenager Kelsi Nielsen. Or so we've heard. Actually, Kelsi would probably be our favorite character in the series. If, you know, we'd actually seen it. Which we haven't.
