Jennifer Lopez and Iggy Azalea keep their "Booty" tame at AMAs

Has pop culture passed its maximum capacity for gluteus maximus? For a few months it seemed as if, when it came to fascination with the female backside, the public's appetite was endless. The phenomenon even inspired some really overwrought think pieces, but we seem to have turned a corner. 

Kim Kardashian didn't break the Internet, but the grotesque spectacle of her oiled-up hindquarters on the cover of Paper magazine might well have broken the spell we seem to have been under.

How else would you explain the relatively tame performance of "Booty" that Jennifer Lopez and Iggy Azalea turned in at the American Music Awards last night?

Oh, sure, they rubbed their haunches together for a fleeting moment, but considering the single-entendre nature of the song (sample lyric: "Big, big booty/What you got, a big booty"), they really reined it in. It certainly didn't live up the salacious introduction from noted butthead Pitbull (who appears on the original recording of the song; Azalea is on the remix), nor to the thoroughly ass-obsessed video.

Then again, it might have been down to ABC's determination to keep the proceedings family-friendly. In a breathless report filed last Thursday, TMZ said "The execs have set the ground rules ... no cracks, no rubbing. There will be a 3-4 second delay, but these shows have a rich history of raunchy performances slipping through ... the cracks. It's interesting ... we're told ABC has not put the kibosh on spanking ... something fairly prominent in the music video. But that's as sexual as execs will allow."

 Have we finally reached Peak Ass? And what will this do to the careers of Nicki Minaj and Miley Cyrus? Only time will tell.
