Katy Perry & Russell Brand: Doing Just Fine

It’s no secret that celebrity marriages take a beating in Tinseltown, but Katy Perry insists that her union with Russell Brand is going very well.

The “Firework” songstress blasted rumors that there’s trouble in paradise with a post on her Twitter page.

Katy tweeted, “Just cause we don’t flaunt our relationship doesn’t mean there’s something wrong w/ it. Privacy is our luxury.”

False stories of infidelity, separate lives, and the like have been surfacing as of late, though Perry says they’re all bogus.
