As revealed by TMZ, Katy and Russell were aware that things were deteriorating but were holding them all the same to give a chance to their marriage.
Rumors that ran for several months on their break were found to be so. Although they denied it and said that the actor is "very happily married", Katy and Russell knew they were on the wrong slope. According to TMZ , the divorce had already been mentioned several weeks ago but they would not be in Los Angeles when it was formalized. It would be for this reason that the beautiful would have flown to Hawaii, while Russell is back in London.
Also, Katy's parents are evangelical Christians, it seems she did not want the divorce itself ! This would indeed have been very shocking for them to consider divorce as totally against nature. So she asked Russell Brand to fill the papers ending their marriage. Following the formalization of their divorce, the actor admitted that he "would always love" Katy and was certain that they "would remain friends."
