American Idol judge Jennifer Lopez seemed to have a bit of a "nip-slip" while presenting the award for best in costume design and makeup during the Oscars last night, but her stylist is claiming otherwise.

The internet is buzzing about whether JLo fell out of her gown for a split second while joking around with fellow presenter Cameron Diaz.

But her stylist, Mariel Haeen, told People magazine that built-in cups in Lopez's custom-made Zuhair Murad gown prevented any wardrobe malfunctions. "The dress fit perfectly to every inch," Haeen told People in a statement. "While the dress did give the illusion of sheerness, joke's on everyone who wishes they saw something!"

Nip-slip, or sheer imagination? You decide. Watch Lopez's reported wardrobe malfunction here:
