But no, it's just a tease for an opera about the star-crossed love between Justin Timberlake and Britney Spears.* Seriously. Apparently.
WE GIVE YOU TIMBERBRIT. And in the event your curiosity hasn't been sated by the audiovisual masterpiece above, here's pretty much everything you need to know about it, courtesy of NPR:
It's a tragic tale that imagines Spears' last concert, in the final hours of her life. Timberlake returns after a long absence to win back Spears' love, but in the end she chooses the audience's love above all else.[Composer Jacob Cooper] began work on the opera by experimenting with a technique called time-stretching. Using digital audio software, he slowed down Spears' songs — and suddenly the light pop tunes seemed hauntingly tragic. Phrases like "Hit me baby one more time" took on an entirely different and more weighted meaning.
*This is one of those times you wish ill-fated teen tragedies ended the way they did in the Shakespeare days.
