Jason Aldean: Yep, That's Me in Blackface as Lil Wayne (PHOTO)

Jason Aldean is copping to going out in blackface and dreadlocks for Halloween.

The country star's rep confirms Aldean dressed up as Lil Wayne for his costume, and paraded around with a group of friends. It's unclear where he was at the time, but the group pic first surfaced on Nashville Gab.

So far, Jason's offered no apology -- and his rep made no specific mention about Aldean darkening his face with makeup.

It's worth noting ... Jason is one of the artists on Jay Z's Tidal streaming service.
