Singer Lee Hyori recently participated in the recording for KBS2 'Happy Together's' 10 year anniversary special that took place on February 25th.

Hyori posted on her Twitter, "The recording started at 10am this morning and has now finished. Although it was tiring, I had a great time with the Oppas. Congratulations Happy Together for your 10 year anniversary."

Before making a guest appearance, Lee Hyori had a surprise phone conversation with singer/actress Uhm Jung Hwa on the episode that aired on the 19th. On that day, MC Yoo Jae Suk stated, "I miss seeing you on variety shows. Since you don't seem to be that busy these days, you should guest on Happy Together", to which Hyori replied, "I'm busy. Plus, I have to go search for missing dogs in the neighborhood."

Fans who saw Hyori's tweet commented, "Will definitely watch Happy Together's 10 year anniversary special. Looking forward to Hyori Unnie's appearance", "Knowing that she'll be on the show, I'm already anticipating it", and "Looks like viewer ratings for the show will skyrocket thanks to Hyori."
