Katy Perry Unfollows Russell Brand on Twitter

During a tour stop in Indonesia, the pop singer quietly deleted her soon-to-be ex-husband from her follow list.

Guess fans shouldn't expect a Jennifer Lopez-Marc Anthony Q'Viva-esque collaboration anytime soon from Katy Perry and Russell Brand. Perry has unfollowed Brand on Twitter.

The pop artist made no direct mention of the move on her feed, which included recent tweets about the late Etta James, a birthday greeting to "Teenage Dream" songwriter Bonnie McKee, and a shout-out to fans in Jakarta, Indonesia, where she performed last night.

However, Brand still lists Perry as one of the 78 people he follows on the micro-blogging site.

She has avoided the media spotlight since news of the divorce broke on Dec. 30. Perry canceled her People's Choice Award appearance and has not spoken to any press about the divorce. The singer stayed mum about the split, aside from a tweet posted Jan. 7 shutting down any gossip. "Concerning the gossip, I want to be clear that NO ONE speaks for me. Not a blog, magazine, "close sources" or my family," she wrote.

Perry has continued to work behind-the-scenes, however. Electronic Arts announced on Jan. 17 that the singer would be doing an "extensive and exclusive creative collaboration" for game franchise The Sims. On Jan 18, Perry released an acoustic version of her sixth single "The One That Got Away," which now seems especially raw in light of the breakup of her 14 month marriage.
