London, Jul 5 (IANS): Singer Katy Perry is said to be doing meditation to cope with stress.
"She chants the mantra 'om' for 20 minutes twice a day with her eyes closed. It's really helped her to move on," dailystar.co.uk quoted a source as saying.
The 27-year-old ended her two-year marriage with British comedian Russell Brand a few months back and is now dating guitarist Rob Ackroyd.
