Justin Timberlake hangs upside down before gigs?

London: Singer-actor Justin Timberlake reportedly hangs himself upside down to get his heart rate going before performing at concerts. The 32-year-old `Suit & Tie` hitmaker apparently has a set routine like two hours of meditation and less talking, which he practises backstage before hitting the stage, reported a website. "Justin is really strict about routine before his gigs. He believes keeping talking to a minimum and meditating gets him `in the zone`," a source said. "The hanging upside down bit gets his heart rate going as last-minute preparation," the source added.
