The anniversary special episode will be packed full of special guests and surprises, and that includes a special panel this week, including Highlight's Doojoon and Junhyung, Girl's Day's Minah, Seventeen's Vernon, and actress Kim Sung Ryung. 

A brand new lineup of masked singers will be competing for the chance to battle against the defending king, 'I'm Gonna Sing', reigning for the past 4 weeks. 

The opening for this week's episode will also consist of a grand-scale performance by a whole crew of former masked singers. Make sure to tune in on April 2 at 4:50 PM KST!
