Child actress Kim Yoo Jung and miss A's Fei may look dainty and slim, but they proved on KBS 2TV's 'Happy Together 3' that they had an impressively large appetite by revealing how much they can eat in the 'Eat and Eat Again' special on December 4.

Kim Shin Young looked at Kim Yoo Jung and said, "You look like you would only eat salad," to which the actress replied, "I'm a glutton.  I binge eat for every meal like any ordinary person," surprising everybody.

She continued, "I eat three slices of samgyupsal (fatty pork belly) at once.  I eat eggs and tangerines without stopping."

The MCs said, "You eat that much, but you don't gain weight?"  Kim Yoo Jung replied, "I'm the type to gain weight.  I eat and then I don't eat; if I gain weight, I don't eat again."

Park Myung Soo said, "Can you eat an entire large pizza?"  She replied, "If I want to eat it, I can eat it."

Kim Tae Woo added, "It's possible with cola," while Kim Jun Hyun said, "If you set your mind on eating it, your stomach can expand," making everyone laugh.

In addition, Fei revealed, "I don't eat a lot at once, but I'm the type to keep eating throughout the whole day.  I often hear, 'You're eating again.'  In China, I eat my mom's cooking well all the time.  My mom's specialty is the duck.  Since elementary school, I could eat an entire roasted duck by myself," surprising everybody."
