The 'idol special' of the MBC singing competition 'Mask King' returned for its third week!

On the February 17 episode, 'Long Princess' was among the talent asked to reveal their identities to the crowd after losing head-to-head singing battles.

The contestant, who had performed a duet of "Cast A Spell" by Park Hye Kyung with opponent 'Princess,' surprised everyone when she took off her mask. 'Long Princess' was none other than popular YouTube beauty guru Risabae, who is famous for using make-up to transform herself into a number of famous faces, including Sunmi and MAMAMOO's Hwa Sa.

During the reveal interview, she gushed about how much she enjoys singing, telling the crowd that she often carries a portable karaoke microphone around with her. She had even brought her favorite of the three she owns - her pink rose microphone - with her to the studio.
