SHAKIRA was robbed by a fan during a concert. The 34-year-old singer was shaking hands with revellers as she performed in Monterrey, Mexico last Thursday when one opportunistic concertgoer snatched her ring from her finger. Although Shakira noticed the robbery - which was caught on camera - she continued performing and did not confront the thief. No arrests have been made and the concert at the University of Monterrey, was her final show in the country. Meanwhile, Shakiras boyfriend - soccer player Gerard Pique - has revealed although he is very happy with his girlfriend, he is struggling to cope with the newfound paparazzi presence that comes with dating an internationally famous pop star.
