Katy Perry is DONE with Russell Brand.

Katy has has unfollowed her soon-to-be ex-husband on Twitter, even though Perry is still one of the 78 people Brand subscribes to via the social networking site.

“She’s limiting those interactions,” a source told Us Weekly. “He’s being so atrocious that she feels like she never really knew him.”

Perry took her “California Dreams” tour to Jakarta, Indonesia, last night in her first public appearance since Brand filed for divorce on December 30th.

“I’m shaking,” Adri said, before leaning in and giving the singer a kiss on her cheek.

“I do as I please now,” says Katy.

“It’s so exciting to finally get to Indonesia. It takes 27 hours from Los Angeles to get here,” Perry said onstage. “You guys have been waiting for so long, it feels like a lifetime.”

When Katy invited her young male fan to join her onstage she said, “I want the first boy to take their shirt off to get up on stage.”

You’re trying too hard, Perry.
