Teen singing sensation and Australia’s Got Talent winner and Jack Vidgen will perform in Wollongong on Saturday.The 14-year-old became a household name almost overnight when he took out the TV contest in May, picking up $250,000 for his efforts.Billed as the next Justin Bieber, he attracts hordes of young - mostly female - fans wherever he performs and dozens are likely to be present when he performs his debut single Yes I Am in the amphitheatre at 1pm.Following his performance, the young star will sign autographs at JB Hi-Fi in Wollongong Central from 2pm. Organisers have said the show will go on regardless of weather and in the event of rain the performance will be moved from the amphitheatre to underneath the bridge link at the western end of the mall, near the Forever New store.
