It would seem that pop star Justin Bieber has unique ways of de-stressing before his concerts. The latest videos on his Instagram account show him playing football with his entourage at the city's luxurious Habtoor Grand Hotel a day before his Dubai concert yesterday. In Mumbai, where he is rumoured to land tomorrow morning for his Purpose World Tour, a source close to the organizing committee confirmed that he would be kicking the ball around at Lower Parel's St Regis, while his crew will camp out at the neighbouring Four Seasons.
