Fans are already looking forward to seeing them on 'Healing Camp', and now 'Beatles Code 3D' has released their own preview of Taeyeon, Tiffany, Sunny, and Hyoyeon on the show! Lim Chang Jung is also a guest for the episode, and it looks like the girls and the veteran singer make a hilarious set!

The girls get honest in the trailer, and Hyoyeon talks about dating (perhaps one of the MCs?). All of them get so rowdy that one of the MCs even jokingly tells the girls, "I think you guys are the problem". 

Check out the preview above!
