The couple – who married in an intimate ceremony in India last month – are keen to do everything they can to ensure their marriage works so have drawn up a list of relationship rules, including buying a £1.8 million apartment in New York that is convenient for both of their work commitments.
A source said: “Russell’s often in London with work and Katy in Los Angeles. They wanted somewhere slap bang in the middle so they never have to sleep apart for more than seven days.
“Russell is aware that many famous couples split because of work demands and he pointed to Brad Pitt and Angelina Jolie as an example of how to make it work.”
As well as agreeing to see each other once a week, another rule created by Russell and Katy is to start a family next year.
The source told Britain’s Grazia magazine: “Another promise is to try for a baby in a year. While Russell is broody, Katy is in no rush, so they compromised.”
Though their new apartment comes with a personal chef, the ‘Firework’ singer has also promised to learn to cook to please her new husband.
The insider said: “Neither Russell nor Katy can cook, but he has told her that one of his favourite things in life is breakfast in bed.
“So Katy has agreed to start making Russell breakfast every Sunday.”
Also among the rules set by the couple are to continue speaking to their relationship therapist once a week and banning alcohol and saucy magazines from their home.
