Recently, a few pictures of IRENE went viral in various online communities.
What caught the eyes of the public was this one dance move from the choreography of 'RBB (Really Bad Boy)', Red Velvet's new title track.

She was supposed to clench her fist except those two fingers but her little finger always sticks out as if it wants to join the party.

Even though it turned out to be a force of habit, this unintended behavior of hers made her fans go wild.

Check out IRENE's most adorable habit yourself!
