Super Junior's Ryeowook and singer Ailee revealed that they will be leaving KBS's "Immortal Song 2." 

On Monday, Ryeowook's representative stated, "Because of Super Junior's busy schedule, Ryeowook will have to completely leave 'Immortal Song 2.'"

The representative continued, "Ryeowook on July 16th, recorded his final performance for the show and will air on the 25th of this month."

Ailee, who is also busy preparing for her comeback album for October will only be temporarily leaving the show. Ailee's representative stated, "Rather than saying that she will be leaving the show, Ailee will be temporarily absent from the show. There is a good chance that she will be returning."

Ryeowook became a permanent member of the show after his performance back in May and has been receiving much love ever since. Ailee became a permanent member back in April and has been named the mascot of the show for her powerful performances.
