Basically, the creator of BreatheHeavy (Britney's biggest fansite) confirmed to the fans that Britney will perform Work B**ch in the dessert this day. The Britney stans were super excited because she hasn't had a TV performance since 2008 and the last time The Army saw her perform was in 2011 with the FF Tour. Also, the guy that confirmed the news knows some of Britney's people and occasionally gave reliable info. The day of the "performance" was crazy, her fans from all over the world were staying wide awake and anticipating her to perform only to find out that all she did was a 2 sec TV interview which she barely even said anything Her fans were super pissed and it created the biggest meltdown by The Army.
This hurt her more than BJ did. Just like the Make Me video hurt the chances of Britney having a successful second single. Whoever thought of this should get sued.
