what was Xtincta's last SOLO single to go top 10 on iTunes ?
You know they would never answer. They will stay pretending that Xtina makes those features hits and bring the viewers in for The Voice even though her album, touring and solo single success say otherwise.
TMCS is grossing 180M+ from what has been announced so far alone, an Asian leg, a 2nd Europa leg and possibly a 2nd leg in Latin America, meaning it's making between $200 - 250 million worldwide.
I would recommend Rihanna stans not to try it ... Their fav is getting her pubic hairs snatched with her flop tour ...
