BUENOS AIRES, Argentina (November 16, 2012)--Fans of Lady Gaga were turning out in all sorts of costumes outside the stadium where she's preparing for a concert Friday night, and they were rewarded with a brief appearance.

Lady Gaga greeted the crowd wearing jeans and a T-shirt and long red hair as she entered the stadium.

Three burly bodyguards kept her well beyond the fans' reach.

The Grammy-winning star also was expected to receive an award Friday evening from the city of Buenos Aires, which has named her an official "guest of honor."

Lady Gaga's "Born This Way Ball" tour is wrapping up its Latin America leg.

She performs next in Santiago, Chile; Lima, Peru, and Asuncion, Paraguay.
