Red Velvet have grouped up in teaser images for their upcoming album 'Really Bad Boy'.

The SM Entertainment girl group are returning for the last of the fall season with a spooky theme, but modern and chic black and gold are also a theme in their comeback concept. As previously reported, Red Velvet are taking on another creepy concept, and the title 'Really Bad Boy' lets fans know it might be a continuation of Red Velvet's previous hit track "Bad Boy". 

Stay tuned for updates!
