She no longer looks like a grandmother in this gorgeous gown, but it does look like she's wearing grannie-panties! Perhaps feeling a little more "exposed" than usual in this back-baring dress, Katie struggled to keep from pulling a Britney as she stepped out of her car and into the Giorgio Armani Prive party in Paris. But her modesty was almost completely unecessary, there's no way she'd reveal much of anything in that girdle! Rachel McAdams, Cate Blanchett and Kelly Carlson also attended the party, but Posh was nowhere in sight!
