haha u guys are so MADDD at mariah, talking about celine beating mariah? her last album was in 08? and she keeps doing vegas shows? mariah has made a whopping 600 million plus dollars from her recordings, and don't forget the royalty checks that pandora and other music shows who cover her music and sell it! not including her christmas season checks. mariah doesn't need to sing anymore! whitney sold more because the public never heard from her till 09! MARIAH IS A WALKING ICON! and for saying she can't sell out arenas? mariah just sold out 4 shows in australia in less then 4 min! and her pearl concerts were sold out to! and her brazil concert in 2010 with over 50,000 SOLD OUT! go somewhere with that bs!
