HOLLYWOOD, CALIFORNIA -- 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, white 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. She infamously turned heads at the 2003 Oscars in a low front and back green Versace dress.
