Why would she ever do a duet with Xtina (which was the question)? She'd never be heard by the legend's legendary belts. Selena would easily overshadow Britney's vocals so she's a clear choice.
Selena shared that she can definitely see the connection between Christina's album and her own, revealing: "That was kind of what I started off Revival as — as some sort of story, I mean that album for [Christina] was incredible. Like 'Beautiful,' 'Can't Hold Us Down' … That's the stuff that I love. That was an album, that was complete."
She said it's a tough question, and she chose Britney not because she's somehow better than Christina, but because Britney's cd was her first cd she bought.
