Katy Perry has blamed Russell Brand for their marriage breakdown
The `Rock of Ages` actor filed for divorce from the pop star in December 2011 but Katy believes Russell`s refusal to come visit her while she was on her world tour is one of the main reasons their 14-month union ended.
When asked by The Sun newspaper if Russell`s lack of visits was the catalyst for the break-up, Katy replied: "Yes, if I could edit it any other way I would but that is exactly what it was.
"I always had plans to make this record (`Teenage Dream`) and usually with a record, you tour.
"Touring is always important to me. It`s like a big IOU to my fans, because I know they are the reason I exist."
It had been speculated that the pair`s marriage imploded because Russell, 37, wanted kids and 27-year-old Katy wasn`t ready, but the pop star insists she can`t even think about having children until her career slows down.
She explained: "Ever since I was younger I wanted to be on stage, singing my songs in a glittering costume. And that happened and is still happening. I have to remember that this is what I wished for and be grateful because there are 500 other girls right behind me that are ready to snatch it up.
"When I decide to become a mother I will just be that. That will be really important to me.
"I want to be delicate with that situation, because I will finally have someone`s life in my hands."
