The FALLIN' hitmaker, who asked Legend to open her tour last year (05), has huge admiration for the artist's authenticity.
She says, "He's special. He's a person that plays and sings and writes his own music, he's not trying to keep up with the Joneses.
"There's nothing more special than to see an artist playing his own music. I think a lot of people are seeking it out - the truth of it."
