Nancy Ajram needs little introduction — not least to her 2.8 million followers on Twitter. The Lebanese superstar is one of the most successful Arab singers of all time, with a total of seven albums and numerous chart-topping singles to her name. In 2008 she was named the best-selling artist in the Middle East at the World Music Awards, and two years later achieved wide acclaim when she sang ‘Wavin’ Flag’ for the 2010 FIFA World Cup. US TV icon Oprah Winfrey has also branded her one of the most influential personalities in the Middle East.
