The British rapper said that his backstage trailer at UK's V Festival was opposite the Just Dance hitmaker's. And he was left shocked by the amount of equipment she takes on tour.
"They have a lot of audio going on. I respect that. I think she has probably spent about four times the amount she has been paid to do this (show) on her set. I respect that absolute disregard for any financial sense. I think it's beautiful," the Daily Star quoted him as saying.
He added: "She has got four Vespa scooters. And her piano is bullet-proof. Honestly, on my mother's life. Her piano is bullet-proof. We found out from her stage manager."
