Pop star Katy Perry was reportedly spotted hugging her on-and-off boyfriend John Mayer at Grateful Dead's concert.
The "Firework" hitmaker was photographed getting cozy to the 37-year-old singer at the concert in Chicago, thus fuelling their romance rumours, reported AceShowbiz.
In the picture, Perry, 30, is seen wrapping her arms around Mayer from behind as they enjoyed a performance by the rock band. In another photo, Perry was caught leaning in to tell Mayer something.
Perry, who divorced from Russell Brand in 2012, started dating Mayer following the split.
Although Perry and Mayer allegedly split earlier this year, the pair was spotted in late April spending time together at Disneyland in Anaheim, California.
