The 28-year-old singer said she has not heard from the funnyman since he messaged her more than a year ago to say their 14-month marriage was over, reported Sun online.
"He's a very smart man, a magical man and I was in love with him when I married him. Let's just say I haven't heard from him since he texted me saying he was divorcing me December 31, 2011," she said.
Although Perry accepts her hectic touring schedule was partly responsible for the failure of her marriage, she cryptically hinted there was more reasons to get apart.
The couple were divorced last year.
Since the split, Perry dated musician John Mayer but confirmed their on-and-off relationship is finally over. She is currently linked to heartthrob Robert Pattinson.
