London, July 6 - Singer Katy Perry has blamed Russell Brand for their marriage breakdown, saying his refusal to come visit her on tour caused their split.

The 37-year-old filed for divorce from Perry December 2011 after 14-months for marriage.

"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," thesun.co.uk quoted Pery as saying.

It had been speculated that the couple split Brand wanted kids but the 27-year-old wasn't ready.

She says she can't even think about having children until her career slows down.
