Amanda Seyfried was greeted with a musical welcome when she touched down in South Korea as a crowd of fans sang her a birthday song. The Mamma Mia! star flew into the Asian country on Tuesday (03Dec13), the day of her 28th birthday, and a large group of devotees gathered at Incheon International Airport to pass on their best wishes. The crowd of around 150 people sang a special birthday tune to the actress, who was also presented with flowers and hand-made cards. She shared her appreciation by taking a picture of one of the cards, which features a drawing of the star and her dog, and uploading the snap to her Twitter.com page. Seyfried was accompanied by her current boyfriend Justin Long on the trip to promote Japanese cosmetics brand Cle de Peau Beaute.
