Britney has 5 so far (...Baby One More Time, Oops!...I Did It Again, Britney, In The Zone, Circus) and "Blackout" was supposed to debut at #1, but Billboard changed the rules literally an hour before the chart was released and she debuted @ #2. :dickhead:
Alicia has 4 #1 debuts too, even her "Unplugged" album opened at #1.
When "Circus" opened at #1 Britney became the youngest female artist in history to have 5 #1 albums and has earned her yet another place in the Guinness Book of World Records.
