In order to show their support for mentor Lee Sun Hee, actor Lee Seo Jin and singer Lee Seung Gi will be making a surprise guest-appearance on 'Star Audition - Birth of a Star 2'. The two will be featured in the episode scheduled to air on the 13th, and they will stop by Lee Sun Hee's 'mentor school' to talk with the mentees. Lee Sun Hee is a label mate to Lee Seo Jin and Lee Seung Gi, and the two personally volunteered to be a part of the program. They will be listening to Lee Sun Hee's proteges sing on the show, and the 'Birth Of A Star' representatives remarked, "The two will be stopping by to cheer on the mentees on the program, and therefore will not be doing any additional judging." "Guitarist Ham Choon Ho will be stopping by the mentor school to serve as a special judge," they continued. 'Birth Of A Star' boasts over 15% of viewer ratings and is one of the top audition programs in Korea. Source & Image: SportsKorea via Nate
