Viewers will be seeing�CNBLUE's Yonghwa and SISTAR's Hyorin on the premiere of�MBC's variety show, 'I'm Your Substitute Angel'. The two idol stars were invited as the first guests on the pilot episode, and they've already wrapped up filming.

The show, MCed by Yoon Do Hyun, Tak Jae Hoon, Eun Ji Won, and KARA's Hara, is the replacement of the short-lived 'Talk Club Actors'. Each week, the four MCs and the guests relay messages for viewers that they're unable to say themselves. The concept of the show, "If you don't say anything, no one will know", aims to help people speak up about what they've been hiding.

The MCs, guests, and crew will also be figuring out how the target moves throughout the day to determine the best plan and place to meet.

On the first episode, Hyorin and Yonghwa helped out a man tell his mother and father-in-law that he actually has four parents. Yonghwa will be the one telling the man's mother-in-law, and Hyorin did her part by showing off her best aegyo to ask the man's boss to let him off work early.

The first episode will air on the 11th at 11:15PM KST! How do you think it'll do?
