In Katy Perry's case, she got a text saying exactly that from then-husband Russell Brand. "He's a very smart man, and I was in love with him when I married him," Katy told Vogue back in 2013. "Let's just say I haven't heard from him since he texted me saying he was divorcing me December 31, 2011."
And it appears that time doesn't necessarily heal all wounds because the same is still true today. During a new interview with The Daily Telegraph, Katy was asked if she's spoken to Russell at all since the divorce. "He hasn't spoken to me since he texted me saying he was filing for divorce," she said. "I don't want to talk about him - my songs will say what I need to say."
As for the cat that she and Russell had together, which they named Rusty (a mashup of their own names), Katy still has the cat, "but I've changed her name to Monkey."
