Katy Perry's romance with John Mayer is rumoured to be back on after the pair were spotted smooching at a music festival.
The Teenage Dream songstress and the US singer-songwriter were thought to have called time on their budding relationship last month after dating for several weeks.
But E! News reports that the pair were seen looking cosy at the FYF concert in Los Angeles at the weekend.
Katy and John were apparently seen kissing as they watched several bands perform, and the rocker - who previously dated Jennifer Aniston and Jessica Simpson - was also seen with his arms around the Firework singer.
The stars were first spotted out together in June.
