Jennifer Lopez arrives at the 84th Annual Academy Awards held at the Hollywood & Highland Center on Feb. 26, 2012 in Hollywood

*Twitter lit up Sunday night with buzz that Jennifer Lopez may have had a wardrobe malfunction while presenting at the 84th annual Academy Awards.

Her stylist, Mariel Haenn, tells People that Lopez’s custom Zuhair Murad gown featured special built-in cups that prevented any “slips” when she took the stage at the Hollywood and Highland Center with Cameron Diaz to honor the best in costume design and makeup.

“The dress fit perfectly to every inch,” she tells People in a statement. “While the dress did give the illusion of sheer-ness, joke’s on everyone who wishes they saw something!”

“The American Idol” judge sported another Zuhair Murad gown for the annual post-Oscars Vanity Fair bash.  See pics below.
