Jay-Z doesn’t really “do” Twitter, but with a new album to promote, he’s making an exception today. Plenty of fans had questions for Beyoncé’s husband Shawn Carter, but as long as we’re apparently considering having Miley Cyrus’ “Party in the USA” replace the current national anthem, could we get some perspective on the former Disney Channel star’s newfound habit of twerking? You know, this:

Jay-Z called out Miley Cyrus and her twerking in his track “Somewhereinamerica.” As it turns out, that clip of Miley Cyrus might not just be nightmare fuel for parents, but the “old world’s worst nightmare.”

Ms. Cyrus confirms via tweet that, yes, she is the old world’s worst nightmare.

So, this twerking isn’t going away any time soon?
