4minute HyunA and BEAST Jang Hyun Seung will be coming back this November with "Trouble Maker."

There is no confirmed date for the comeback yet, but they are trying to make it for the beginning of November.

This duo first released "Troublemaker" in 2011 and gained much attention.

HyunA has recently been posting pictures on her twitter that looked like behind the scenes of another "Troublemaker" song in the works, making fans curious.

Their agency has made no formal announcements either, which has made this an even bigger issue.
