London: In a bid to overcome stage fright, singer Robbie Williams is preparing for his global tour by taking yoga classes.

The pop star is all geared up to go on tour with ‘Take That’, rejoining the band after 15 years, and is practising strenuous Bickram Yoga to calm his nerves, reported a website.

"Rob suffers from crippling anxiety and has been worried about the lads' forthcoming concerts. A pal suggested Bikram yoga to refocus his pent up energy and handle stress more effectively," said a source close to the singer.

The 38-year-old singer has been attending the sessions for the last three months, which see him strike a number of meditative poses in a room heated to 40 degrees centigrade.

"After a couple of sessions he was hooked and sweating like a wildebeest. While the others have stuck to the gym or pool, Robbie's been using meditation and yoga to help his stage fright and to keep sane on tour," added the source.
