Oddly enough, it seems his self-imposed responsibilities extend to trying on wedding dresses.
In a picture posted on Perry's Twitter page last night, Brand wears one of his signature outrageous expressions -- along with a veil and an awful '80s-style wedding dress (we're talking heavily embroidered long sleeves, puffed shoulders, pleated princess skirt, and a sweetheart bodice with a mesh modesty panel).
Perry attached the caption "Bridezilla much @rustyrockets?" to the photo.
It all backs up what Perry recently revealed to MTV News on the orange carpet at the Kids' Choice Awards (at which she was slimed!).
"He's a total bridezilla. He's like a freak, man," she said. "You should see -- he's always, like, buying bride magazines. Every time we go out for breakfast, he's like, 'Can we just stop and get a bride magazine?'"
We just hope she doesn't take his advice on bridal fashion.
