Heat magazine had previously reported that the Teenage Dream hitmaker and Brand were heading for a split, and that Perry was "worried it could be the end of the road" and she was "thinking of taking a break" from their marriage.
A supposed friend of Katy's also told the publication that the 26-year old had said: "It would be heartbreaking if we didn't make it to our first wedding anniversary, but our situation is pretty bad."
The Last Friday Night singer has since taken to Twitter to slam the allegations, telling her followers: "Just cause we don't flaunt our relationship doesn't mean there's something wrong w/it. Privacy is our luxury. #tabloidsrtrash #gossipisgross."
Brand then responded to his wife, tweeting: "You tell em Mrs Brand! In Britain we're currently dismantling the scum media so I'm not tuned in to their brain-farting."
