Katy Perry Cozies Up to John Mayer at Allison Williams's Wedding

Katy Perry was spotted cozying up to her famous ex John Mayer at Allison Williams's wedding in Saratoga, WY, over the weekend. The duo sat in front of Lena Dunham and Jemima Kirke and kept close during the ceremony, flashing sweet smiles and holding hands, which added more fuel to reports that they have rekindled their romance after splitting in February 2014. But before letting us jump to any conclusions, People reported, "They had both agreed to attend the wedding because they are dear friends with the bride and groom, but they are not back together. It was an emotional wedding, and they held hands but only because they will always care about each other." A source added, "They were happy to see each other and spend time together at the wedding, but they are not a couple. They're both going to go out with other people, and they want each other to be happy." Keep reading to see the exclusive photos from Katy and John's reunion.
