miss A's Fei found a happy surprise awaiting her on her birthday!

Arriving on the set of her dance audition program, 'Dancing With the Stars 3', Fei was greeted by her co-workers holding up a massive banner, displaying her beautiful face along with the words "Happy birthday".

She seemed to be surprised at the generosity of her fans and her co-workers. "Three say A's made this birthday cake," she posted to her Twitter earlier. "Thank you so much^^ also thank you to all of the AQ family who came to support me^^"
