If there's one anniversary to remember, it's Blackout 's -- Oct. 25, 2007.

One can only scratch the surface when it comes to the successes of Blackout.

Britney Jean Spears led the charge in 2007 as the record's executive producer, and years later, Blackout was raved as possibly the most influential pop record within a five-year period, after which it was inducted into the Rock and Roll Hall of Fame Library.

But much of what fueled the interest in the 2007 music project was the gossip.

Speculation will always surround the abandoned "Gimme More" video concept, the alleged basket of J.R. Rotem tracks that nearly made it to the record and the he-said-she-said talks of a Blackout tour.

But while there's a lot of lost info out there, plenty has surfaced. So, celebrate this year's Blackout anniversary with the record's lesser-known facts and mysteries.
