The couple has rarely been seen together and reports suggested they were planning a trial separation.
Perry and Brand recently purchased a new Los Angeles home together and the singer has now spoken out in a bid to silence gossip about their relationship, revealing they are just trying to keep their private life out of the public eye.
In a post on Twitter.com she writes, "Just cause we don't flaunt our relationship doesn't mean there's something wrong w/ (with) it. Privacy is our luxury. Tabloids r (are) trash. Gossip is gross."
Brand backed his wife's comments, writing, "You tell 'em Mrs Brand! In Britain we're currently dismantling the scum media so I'm not tuned in to their brain-farting."
