HOLLYWOOD, Calif. - Uh oh, J-Lo. Jennifer Lopez appeared to have a wardrobe malfunction while presenting the Oscars for costume design and makeup with Cameron Diaz. Clad in a low cut, Zuhair Murad gown that looked like it might have been painted on, a bit more of her breast than she might have liked seemed to show. Twitter's abuzz about it, no comment from the Academy or Jenny from the Block yet.

It wouldn't be her first risque Oscar move. She infamously turned heads at the 2003 awards in a low front  and back green Versace dress.

Whether or not it happened, it's already got a Twitter handle. @Jlosnipple has more than 500 followers and counting.

UPDATE: Lopez's stylist Mariel Haenn responded t0 the reports in a statement:  "The dress fit perfectly to every inch," she said, saying that it included built-in cups to prevent any slips: "While the dress did give the illusion of sheer-ness, joke's on everyone who wishes they saw something!" In a tweet to this reporter, she added, "If u thought that dress was hot, wait & see what's next!"
