Rebecca Black says 'gay sex' helped her survive Katy Perry's gruelling tour schedule

Rebecca Black says "gay sex" helped her survive Katy Perry's gruelling tour schedule.

The Friday hitmaker, 28, hit the road with the 40-year-old pop megastar over the summer on her Lifetimes Tour, which meant she was performing in arenas for the first time as well as DJing as festivals in between gigs.

Asked how she coped with the schedule, she told PEOPLE magazine: "I have said it once, and I'll say it again.

"It is the gay sex that I am so blessed to have that I can look forward to."

Quizzed on who she's been getting intimate with, Rebecca teased: "My girlfriend."

She didn't give any more details on her partner's identity.

The recent tour was the first time the Sugar Water Cyanide singer was playing venues with over 10,000 capacities each night, and she was "overstimulated".

She explained: "I was so overstimulated the first night and so scared, and by the end it felt so like redeeming to be able to get on and be like, 'This is just another show'.

"It was so much fun. But it was crazy."
