The couple had a series of huge bust-ups over her partying and boozy lifestyle in the run-up to the collapse of their 14-month marriage.
Comedian Russell has beaten booze and drugs addictions and apparently wanted to shun the Hollywood clubbing scene and start a family with the singer.
But Katy reportedly didn't want to become a "Hollywood housewife". A source close to the couple said that Katy took off her wedding ring and handed it back to Russell after one last devastating row a week before Christmas.
The singer thought she had called her husband's bluff and he would come running back. But it was apparently the final straw for Russell, who simply shrugged his shoulders and flew home to his mother Barbara.
The couple spent Christmas 7,000 miles apart -- Katy in Hawaii, Russell in Cornwall -- before he instructed his lawyers to start divorce proceedings on Friday.
Insiders also added that couple had marriage counselling to try to avoid a divorce while keeping up a public pretence that they were happy together.
It remains unclear whether the decision to end the marriage was mutual.
