Katy Perry splits with John Mayer again?

Los Angeles: Singer Katy Perry has parted ways with singer John Mayer again after he couldn't commit to their relationship, said a source."John just can't commit, and he kept luring Katy back with promises that was going to change, but then he didn't. Katy was pretty crazy about him, so she kept giving him another chance," radaronline.com quoted a source as saying.[caption id="attachment_483378" align="alignleft" width="380"] Reuters[/caption]Mayer, 34, and Perry, 27, were together from past couple of months but Mayer was not giving the kind of attention expected from him."John liked Katy, so he wanted to keep her in his life, but it just wasn't up to Katy's standards. She needs the guy to be on board 100 percent and she was sick of John disappearing for five days at a time, then booty calling her, then straightening up and treating her well, only to go back to his old behavior a few days later," the source added.IANS
