Jang Yoon Jung to step down + Hyorin to join as guest MC of '1000 Song Challenge'

As Jang Yoon Jung is expecting a child in June, she will be leaving SBS's '1000 Song Challenge'.  To help fill in for her, Hyorin will be brought in to join the show as a guest MC for four weeks.

Multiple broadcasting reps told TV Report on March 31, "Jang Yoon Jung wrapped up her last recording of 'Challenge 1000 Song.'  Hyorin was appointed as the guest MC of 'Challenge 1000 Song' as Jang Yoon Jung's temporary replacement."

Starship also confirmed in a phone call with Tenasia, "Hyorin has been appointed as the MC... Starting from the April 20th broadcast, she will be appearing in it for 4 episodes."

Jang Yoon Jung is expected to return to activities in September, so it's still being discussed whether a new permanent MC will be brought in later or if the singer will return to her position after a series of guest MCs.
