Justin Bieber surprised his mom (Pattie Mallette) during his sold out Johannesburg concert in South Africa. He brought her on stage and serenaded her with his hit song entitled, “one less lonely girl”. “I love you mom” Justin said. It was a very touching and proud moment especially for Pattie and for beliebers at the show and beliebers that saw clips and read the headlines from this night. A proud and happy moment for Pattie indeed. Justin Bieber is also presently preparing for his 2013 concerts in the U S A.
