Perry says all is fine with Brand

London: Singer Katy Perry has brushed off reports that her marriage to Russell Brand is in trouble, insisting they are keeping a low profile to maintain their privacy.

"Just cause we don't flaunt our relationship doesn't mean there's something wrong. Privacy is our luxury. Tabloids are trash. Gossip is gross," she posted on her Twitter account.

The couple married last year in India and since then they have been dogged by rumours of rift, reports contactmusic.com.

Brand backed his wife's comments: "You tell 'em Mrs Brand! In Britain we're currently dismantling the scum media, so I'm not tuned in to their brain farting."
