Not so fast Katy Perry...

Yes, we were briefly blinded by your beau John Mayer's Willa Wonka-style get up at last night's Grammys, but we still noticed something missing from your after-party outfit.

Well, technically two things.

The "California Gurls" songstress showed off the girls in a Gucci's Resort gown but then the clock struck midnight and—poof!—they were gone.

Ok, so maybe she just changed into a more subdued dress, but the matching greens and floral embellishments made us do a double D double take.
