Hyoyeon's birthday is on September 22 but she reserved the day September 20 to celebrate her birthday in advance with her fans. And now she is 27 (in Korea).
The Hyohunnies gathered and celebrate the awesome day of the 'dancing machine'. Fans are also tweeting #Happy27thHYONCEday & #효연아생일축하해 to commemorate this day.Held at SMTOWN COEX (same venue with the previous celebrations of Soshis birthdays), it is said that the tickets were sold out after few minutes that it is open for purchase. Hyoyeon who knows how to party wears the clothes from the 'Lion Heart' music video.
During the party, Hyoyeon revealed that the Girls' Generation members wants to wear their costumes of the 'Lion Heart' but they couldn't so she wears them to show to the fans. But she answered in another question that jeans and shirts are her choice of clothes and the dress makes her uncomfortable.
She also introduced the manager oppa (above?) as the Lion guy in their appearance in Music Bank. Hyoyeon also gave some juicy info about the planned concert and many other things. You can check some fans account here.
