He commented: There was this huge scandal that originally "Halo" was meant to go to Leona. That was never the case ... That song was written for Beyoncé. What happened was that Beyoncé waited long enough to record that song ... I thought this would be a brilliant first single for Leona, which it would have ... What I did was foolishly say to Leona's camp, "I have it on hold for another A-list artist and I'm pretty sure they'll take it, but if they don't, I just want to know if you like it enough to consider it".
