HIGH SCHOOL MUSICAL star OLESYA RULIN has started taking piano lessons, after faking her musical skills in the DisneyTV movies. The Russian beauty, 21, plays composer/pianist Kelsi Nielsen in both High School Musical movies and hopes to be able to play the instrument by the time they start filming the third movie next year (08). She says, "I cannot play the piano so the scenes were pretty much staged. But it has inspired me to learn so I have been taking lessons. I'm becoming quite good."
