Just hours ahead of the release of their 2nd full album 'Perfect Velvet', Red Velvetsaid "Peek-A-Boo" with a final set of individual teaser images.

Each of the members pose with the gesture which will stand as the signature move for "Peek-A-Boo", with a right hand creating a peep hole over the right eye. The girls also held their comeback showcase earlier today, and will be releasing their full album, alongside the MV for "Peek-A-Boo", later on November 17 at 6PM KST.

Do you think "Peek-A-Boo" will be another girl group hit?
