Girl group Girls' Generation's member Seohyun self-promoted their new song "Mr. Mr".

Today, Seohyun posted on her Twitter, "Girls' Generation's teaser is out! Have you ever heard of 'Mr. Mr.'? If you haven't, gogo now!" along with a picture.

In the picture, Seohyun has red lips with smokey makeup on. She seemed to be in the outfit for the "Mr. Mr." music video, as her bracelet also said the title of the song.

Internet users who saw this commented, "Girls' Generation is finally coming out," "I wonder what the concept this time is," etc.

Girls' Generation will be releasing "Mr. Mr." on February 19.
