Katy Perry denies rocky patch
Katy takes to Twitter to quash rumours that her and Russell Brand's marriage is in trouble.
The 'I Kissed a Girl' star reacted angrily to the recent rumours suggesting that her marriage with Brand is on the rocks.
She tweeted to her 8 million+ followers that the fact they haven't dominated the headlines recently has no bearing on the state of their relationship.
Perry and Brand married in India in October last year and the 'California Gurl' hinted at the time that they had no plans to release details of their relationship to the public.
She told an Aussie radio station: "People have all these ideas about my relationship and my wedding and there is so much speculation. I'm not a traditional type of person in general but after we get married we've decided we're not going to talk about the relationship."
Katy is currently on her 'California Dreams' world tour, while Brand is in Miami filming his new movie Rock of Ages .
California Gurl has been named as Billboard magazine's 'Woman Of The Year' for 2012.
