According to LOOK magazine, Katy went out on a date and had a blast with John Mayer one night before she met her future and now ex-husband Russell Brand.
Katy and John apparently had a blast together and wanted to hang out again. All of those plans were shot down after she met Brand the next night at the 2009 MTV Video Music Awards. Poor John.
Since her divorce from Brand earlier this summer, Katy has been spotted out and about with John Mayer. The two have been seen together all over Los Angeles, instantly sparking dating rumors.
Perhaps she made the wrong choice back in 2009? Mayer's previous flings, Taylor Swift and Jennifer Aniston, would probably say no.
