Blackjacks, brace yourselves accordingly.

While CL's been bopping around in the studio with Skrillex, Diplo and a whole troupe of other talented friends while working on her much-buzzed about, frequently delayed North American solo debut, it seems you can't keep a 2NE1 member away for too long: The group is reportedly preparing for a K-Pop comeback on November 21.

YG Entertainment posted a teaser for a mystery comeback days ago ("Who's next?" they wrote), set to debut on November 21 at 21:00 — which, if you can read between the lines, certainly screams 2NE1.

Particularly observant (and/or obsessive) 2NE1 fans have noticed a string of hints along the way to add fuel to the comeback fire. Also, YG has reportedly officially confirmed the news, although what the troupe is coming back with — whether it be a single or an album — is still TBD.

The girls, who recently won PopCrush's own Battle Of The Bands, have not released music together as a troupe in well over a year since since June 2014's Crush, including hit singles "Come Back Home" and "Gotta Be You." It's about time to add more hits to that discography.

Set your alarm clocks for November 21: The girls are coming home.
