TEARS flowed and screams echoed around Lanseria International Airport on Tuesday night when American singer Lady Gaga arrived."I can’t believe it happened…I saw my idol. I’ve waited a long time to see her, it’s the best feeling in the world,” Bornman de Villiers, 24, said while sitting on the floor crying like a baby.Some people had been at the airport for many hours to catch a glimpse of Mother Monster, as she is also known to her fans.Stefani Joanne Angelina Germanotta, who goes by the stage name of Lady Gaga, was visiting South Africa as part of her ‘Born This Way’ world tour.Hundreds of schoolchildren were there. People held up posters reading "Welcome to S.A Gaga” and "We love you Lady Gaga”.Outside on the viewing deck fans chanted "Gaga, Gaga, Gaga” when her plane landed around 19:30.About eight bodyguards dressed in black and several more police officers escorted her.An airport official stopped her from entering the arrivals terminal where fans had formed a tunnel for her to walk through.Disappointed fans screamed and shouted."I can’t f**king believe I had to wait all day and I couldn’t see her,” one man said.A woman added: "How could the police do this to us? We waited for hours.”People then ran to the airport gate in a hope of seeing her convoy of six Mercedes-Benz Vito vans, three black and three silver leave.Gaga, however, made her entourage turn around and spent about five minutes signing autographs and smiling for the cameras."She came back in style for the people who stuck around for hours waiting for her,” Lweendo Muntanga, 20, said."Mother monster cares about her little monsters,” said Dustin August, adding that he was "mind-blown for ever”.Agencies
