In case you're wondering how Katy Perry might dress for, you know, a casual stroll in London in front of hundreds of fans, you're lookin' at it!

Does this girl do anything small? Do we want her to?

For the premiere of her upcoming feature film Katy Perry: Part of Me, the pop superstar paraded across Leicester Square wearing a frilly Marchesa frock crisscrossed in gold. There was no sign of cupcakes or whipped-cream cans on her boobs, but the onetime Mrs. Russell Brand still looked good enough to eat.

The voice behind "Teenage Dream" offered fans a bold look from head to toe, decking out her eyelashes in red, white and blue, sweeping her purple hair into an updo and somehow managing to get away with silvery shoes paired with a gold-tone dress.

Bravo, Katy, but now we want a cupcake.
