Officials with the Gwinnett County Arena are warning parents who paid up to $2,500 for Hannah Montana tickets that some of the tickets may be fake.

The Arena's Chris Hendley says officials have tried to warn people from the time tickets for Wednesday's show went on sale to be careful about buying tickets. Hendley says the Arena can only guarantee tickets sold through Ticketmaster.com, the arena's own phone lines or through the box office.

The face value of the tickets sold is $66, but some people have paid from $500 to $2,500 to get the tickets from other sources.

Officials say there's NO way to know whether the tickets are real until the concert, which begins at 7 p.m. Wednesday at the Arena in Duluth. Traffic in the area is expected to be heavy.
