After proving he can handle headlining an arena at The Pop-Con at Nassau Coliseum last month, Justin Bieber has announced a summer arena tour starting at the XL Center in Hartford, Conn., on June 23. The “My World” tour stops at Madison Square Garden on Aug. 31.
    Though tickets don’t go on sale to the public until March 27, Bieber is using the tour as a way to re-launch his fanclub at www.bieberfever.com, where members can get their hands on tickets starting Thursday. It’s part of the run-up to the sale of his repackaged debut, now called “My World 2.0,” with new songs including the hit “Baby” in stores Tuesday.
