Did hundreds of millions people get to see a whole lot more of Jenny from the Block than she intended (it might have been even more than what was seen at the 2000 Grammys!)? Jennifer Lopez made a splash while presenting at the Oscars: As MaintainYaBrian Tweeted, "I just saw a piece of J-Lo's #Areola. My. Life. Is. Complete." Although there's an anatomical debate: Per MattGoldich, "J-Lo's butt no longer her most famed body part. #Oscars #Nipple"

Michael Suen sums it up, ""J.Lo's" is now trending worldwide. There's an ongoing argument as to whether the object/hashtag in question is #nipple or #areola. #Oscars"

For what it's worth, the dress is by Zuhair Murad. And LAist is liveblogging the Osacrs: Check out video of Sacha Baron Cohen dumping Kim Jong-Il's ashes on Ryan Seacrest and musings from the Oscars press room.
