Someo of you guys don't even know what you're talking about.
1) Femme Fatale is not a flop album, it was just an average basic album on the current climate of music bussiness, it was disappointing , but I don't think Britney has ever experienced in her career what a real hardcore flop album is. Despite all the mess with Femme Fatale, Britney is still in a fantasy world , with 7 albums already she still doesn't know how is to struggle to reach the 500K WORLDWIDE with an album like it has happened to lots of artists in the bussiness with less albums out.
2) Rihanna is not a stadium artist

, I checked for her Diamonds tour dates, and the 90% or 95% of them are ARENA dates, and just a few stadium dates on the countries she is most popular at extreme low / cheap prices.
