Yes, yes we've heard Jennifer Lopez's explanation of what appeared to be a nip slip at the Oscar's Sunday night.  Her stylist and she at first said that it was the inner mesh lining of the dress, then I heard it could have been a shadow, then I heard it was some of that Hollywood Tape that "keeps things in place for us ladies."  If you ask me, and the rest of America, it was clearly a nip slip! 

Last night on American Idol, it appears that Steven Tyler agreed, and HE would be the expert on nips and slips!

Judge for yourself...
