Katy Perry is not having a great week. First of all, she and John Mayer have ended their inexplicable romance a second time, multiple sources tell Us. They first got together last year and quickly split, but reunited in time for Perry to bring Mayer home for Christmas. Sources say the breakup may not be permanent this time around, either: "It's not over until it's over," says one. "She's leaving the window open," says another. Why the split? "They have both been so focused on work," explains the latter source.
And on Monday night, ex-husband Russell Brand dissed their union on an XFM radio show, the Huffington Post reports. "That marriage was shaky from the get-go, before I’d even got off the elephant," he said, recalling the unconventional entrance he made to their wedding. "It was a drag, man," he continued, according to the Sun. "Let me tell you a thing about marriage. Marriage is a bond that can last up to 14 months. This is a sacred 14-month arrangement."
