Saratoga, Wyo. – September 21, 2015 — (UPI) — Katy Perry and ex-boyfriend John Mayer cozied up at Allison Williams and Ricky Van Veen’s wedding Saturday.
The 30-year-old pop star and 37-year-old singer appeared to be back on again as they held hands during the nuptials. A source told People magazine the former couple are “definitely back together.”
“John and Katy looked happy,” the insider said. “They held hands and sat next to each other during the wedding ceremony.”
Williams and Van Veen have been together since 2011, and married at the Brush Creek Ranch in Saratoga, Wyo. Perry and Mayer reportedly both performed at the wedding.
Perry and Mayer had an on-again, off-again relationship from 2012 to 2014, and stepped out with Williams and Van Veen in January. The pair sparked romance rumors again in July when they attended a Grateful Dead show together.
The pop star last released Prism in October 2013, and will kick off the Latin American leg of her accompanying Prismatic world tour Sept. 22 in Lima, Peru. Mayer released his sixth studio album, Paradise Valley, in August 2013, which debuted at No. 2 on the Billboard 200.
