The second time wasn’t the charm. Pop singers Katy Perry and John Mayer have split for the second time, Us Weekly reported on Tuesday. They broke up for about a month last year. Perry is currently recording her third album, while Mayer is prepping for his upcoming tour. Both have some high-profile breakups in their past: Perry and Russell Brand divorced in February 2012, while Mayer has dated Jennifer Aniston, Jessica Simpson, and Taylor Swift.
