The musician, originally from West Kilbride, in Ayrshire, has already won a Classical Brit as the Young British Classic Performer in 2008.
She attended and performed at the Royal Albert Hall event last night, which was hosted by Myleene Klass.
Other winners included the Oscar-winning Welsh actor Sir Anthony Hopkins who took home a Classic Brit Award after one of his compositions featured on the album of the year.
The Oscar-winning star attended the ceremony with his friend, violinist Andre Rieu, who recorded one of the actor's works as the title track of his album And The Waltz Goes On.
Sir Anthony said: "It's a dream come true for me. Andre's a superb musician, a terrific showman and a wonderful violinist."
