Just when you thought you were done explaining Skrillex and Diplo to your mom, now they're teaming up to form EDM supergroup Jack U. Ugh!

Fans were scratching their heads after they spotted the band's name on Mad Decent's Block Party line up. "Who is Jack U?" And then Diplo took to Twitter to clarify:

So maybe the word "supergroup" is a bit extreme. It could be that Jack U is what Diplo and Skrillex call themselves when they perform live together. Or it could be they really are forming an entirely new group (that will undoubtedly take over the haircut world and the booty-popping world at the same time). 

Skrillex and Diplo are old pals. They released the single "Amplifire" together back in 2011, and they teamed up with fellow DJ A-Trak earlier this year for their collective POTATO project. POTATO, according to their Twitter account, is an "Electronic Music Network curated by @Skrillex @Diplo and @ATrak. Audio and Video Premieres, Tour Docs, Original Series and more."

Mad Decent's Block Party, featuring Jack U, travels through North America this summer beginning July 19 in Calgary.
