Los Angeles - Katy Perry and Russell Brand have put themselves on a diet.
The pair - who tied the knot at the luxury Aman-i-Khas resort in Rajasthan, India, last month - are determined to get fit and feel healthier, and so have cut out all wheat and dairy until the end of this year.
A friend of the couple said: "Katy and Russell are taking care of themselves and are on a mission to get fit. As well as cutting out wheat and diary, they're on a diet of raw vegetables, tofu and pulses.
As well as their special diet, the vegetarian comedian and his pop star wife also appear to have picked up some health tips during their recent stay in India.
The source explained to the Daily Star newspaper: "They're both drinking loads of pineapple juice and are obsessed with Indian green tea which is full of anti-toxins and great for weight loss."
However Katy and Russell's new health kick may not last until the New Year as the pair are said to be planning a fun-filled family Christmas in London.
The insider revealed: "Katy and Russell are trying to get their families together for their first Christmas as husband and wife. Katy thinks a white Christmas in London would be romantic.
"They are hoping to have a proper knees-up with the whole of Russell's family. Katy's mum and dad are hoping to come to London as well."
