Ho, ho, ho! Looks like it's going to be a very Merry Christmas for Justin Bieber and Chris Brown -- who were getting in the holiday mood with their rumored pieces Hailey Baldwin and Kendall Jenner. The foursome were chillin' and illin' in Washington after Chris’ show. We have a feeling this fantastic four is up to no good!

And BTW: where is this motley crew hanging out? A drug den? Or a hipster lounge that's supposed to look like a drug den? Either way -- we hope they brought hand sanitizer.

Kendall, who is rumored to be dating Brown, and Hailey, who is reportedly Bieber's newest fling, both struck a pose in matching crop tops, leather jackets and drop-crotch pants. Is this the new slutty girl uniform and no one told us?

We don't think Karrueche and Selena are gonna like this double date!
