In the upcoming episode of Happy Together Season 3 on May 19th, it was revealed by Lee Hyori that Yoo Jae Suk's favourite idol girl group member is After School's UEE. During this episode, Lee Hyori revealed, "Yoo Jae Suk has a great interest in female idols, so much so that he knows every little detail about them. And he would always only talk about female idols." And this should not be strange if you are a frequent follower of Family Outing. And Lee Hyori went further by revealing, "Yoo Jae Suk's favourite is UEE from After School. You can see that during the filming of Family Outing last time, he would be the only one clapping enthusiastically for UEE." Rain did not want to be left out of the fun and asked MC Yoo, "Who would you save if Goo Hara and Lee Hyori fell into the water at the same time?" You will however have to tune in on May 20th for the answer!
