No surprise there, since the singer has worn the brand many times before.
But what did the dress look like exactly?
Though an official press release from the fashion house confirms Katy wore a design from its collection, reps "[refrained] from sharing details on the gown in order to respect the intimacy of the event." That is so not cool.
Us reports that the gown was dove gray with lace sleeves, so could the California Gurl have chosen this dramatic, sparkly gown that walked the spring 2011 collection runway?
It's a definite possibility.
Whether it is or isn't the one, we're dying to see how the wacky (but much improved) fashionista wore on her big day! How about you?
