14 of 143: Singers Katy Perry and John Mayer called it quits after 'a couple months of casual dating,' Us Weekly reported on Aug. 23, 2012.

The two have not commented. They sparked romance rumors in mid-June and have been photographed and spotted together several times since then but never confirmed publicly that they were involved romantically.

Perry split from ex-husband Russell Brand late last year. The British comedian cited "irreconcilable differences" in the documents, which were filed in a Los Angeles Superior Court on December 30, 2011. The couple had no children together.

In April, she was linked to Robert Ackroyd, guitarist for the band Florence + the Machine. The two reportedly stopped seeing each other in May.

Mayer has previously been linked to Jennifer Aniston, Jessica Simpson and Taylor Swift. In the past, Mayer had been very open about several of the women he has dated.
