According to Us Weekly, the singer is only talking to Russell over the phone or on email. "She's limiting those interactions," a source tells the mag about the couple's relationship following their split. "He's being so atrocious that she feels like she never really knew him."
Russell still currently follows Katy on the social networking site, so he's getting plenty of updates on the singer's career. The 27-year-old just performed in Jakarta, Indonesia and shot an ad for Adidas.
Since the news of their break-up, Katy has only made one statement via Twitter. She wrote: I am so grateful for all the love and support I've had from people around the world. You guys have made my heart happy again."
She added, "Concerning the gossip, I want to be clear that NO ONE speaks for me. Not a blog, magazine, 'close sources' or my family."
