Yup, they went there!
As this season's Top 13 men performed live for the first time, judges Lopez, Tyler and Randy Jackson fawned over the likes of Jermaine Jones, Aaron Marcellus, DeAndre Brackensick, Eban Franckewitz -- and Jeremy Rosado, whom Lopez called "blessed."
It was Rosado who moved Tyler to tug at his shirt and expose his left nipple in a gag host Seacrest called an "Oscar reenactment."
Lopez -- whose Zuhair Murad dress at Sunday's Academy Awards sparked countless tweets and web posts -- was heard protesting off-camera "There was no nipple!" as the crowd laughed and cheered.
