Katy Perry and John Mayer Hanging Out Again

Katy Perry was spotted out and about with John Mayer over the weekend. After a dinner date in Beverly Hills, the Daily Mail reports that Mayer spent the night at Perry's home, where he didn't emerge until 4pm the next day. No word on whether or not the couple is officially reuniting, but you can be sure that Perry was doing a lot of laundry after Cooper, err, I mean Mayer left.
