On an upcoming episode of Happy Together, T-ara's Jiyeon and Hyomin made special guest appearances on the show. Much to fans delight, the two shared funny stories and some interesting facts about one another. Hyomin revealed on set that Jiyeon had to dress up as a ghost for one of her dramas and one time came straight to the T-ara dorms in her makeup and costume. When she appeared, she slowly cried out for the members and surprised them all for a quick scare. This slightly embarrassed Jiyeon but Hyomin didn't stop there as she revealed that the two share a bunk bed together. Hyomin said that Jiyeon would weird her out even more by randomly talking in her sleep at night. This brought much needed laughter on set and made the MCs realize that Jiyeon is very young. The MC's then asked her, "Wasn't the sexy concept a burden to you?" Jiyeon confessed saying, "It's a bit awkward but I try to practice sexy expressions by learning from Hyomin." With this, Hyomin demonstrated the sexy expressions and got the whole set hot and bothered. Either that or it was the sauna. [gallery] This episode is scheduled to air on the 18th.
