This year's annual 'Ground Forces Festival' is looking to be quite special!

It's been confirmed that TVXQ's Yunho and JYJ's Jaejoong will be taking part in the '2015 Korea's Ground Forces Festival'! On the other hand, JYJ's Yoochun, who was previously thought to take part in the festival, will not be.

The festival's representative told Star News, "Yunho will be the 'Ground Forces Festival' MC this year. He will be working with TV personality Choi Song Hyun. Jaejoong will take part as a vocalist, and is set to sing a song. Yoochun will not be taking part."

This is some pretty exciting stuff as it has been a long time since Yunho and Jaejoong have been at the same place at the same time!

The festival has been an annual event since 2002 and this year, it will take place from October 2 to 6. 

You can also catch a glimpse of Jaejoong in the making-film for this festival below (around the 0:45) mark.
