Baby One More Time is Spears' most successful album, selling over 30 million copies worldwide, making it one of the best-selling albums of all time and the best-selling album by a teenage solo artist.
Britney's team is just way too money hungry. The amount of money they're gonna make off her Vegas thing with such little effort (and regardless of the fact if it fails) is more than she'd make off a huge world tour. If anything, you'd think the Beyhive would support it since they're all about money and endorsements.
It would be quite lol worthy if Katy blocks Gaga, Britney, Beyonce, and everyone else. Her sales are insane. The massacre when her album sells 232k in its first week is gonna be quite hilarious too doe.
