On February 4, Rainbow's Woori, who is currently promoting as part of the subunit Rainbow BLAXX, posted a bare face selca onto Twitter, which unintentionally set off a whole deal about a past image of her bare face from when she appeared on KBS 2TV's 'Sponge Zero'.

In this recent selca, half of her face was revealed as she laid in bed, showing off her radiating skin and perfect features despite the lack of makeup.  She wrote, "I want to sleep early today. Goodnight."

Her previous appearance on 'Sponge Zero' was then dug up. In the screen capture below, she shows off her bare face on the left and then her transformation after putting on makeup on the right side. She said jokingly on the show, "I participated because they said they would do my makeup prettily, but I was tricked," to everyone's amusement.

In relation to this, Woori turned to Twitter to address fans once again on February 6, "Can't you please forget about 'Sponge' now?" and uploaded another picture of herself with no makeup.
