Chris Brown apparently got into a little fender-bender this weekend -- and while the scrape to his sports car will probably buff right out ... that doesn't mean he was happy about it.

The singer was hitting the town very early Sunday morning in Hollywood -- leaving The Nice Guy after a little partying, we're told -- and on his way out ... he seems to have bumped into another vehicle that left the front of his Lamborghini with some major scuff marks.

The fact that his whip is white makes the black marks all the more noticeable, of course, and it looks like Chris stopped to exchange info with whoever it was he might've tapped.

He certainly looked frustrated at the moment -- but handled his biz and went on his way.

The next morning, however, Chris seems to have realized the extent of the damage -- 'cause he was photographed looking a little heated as he appeared to be addressing the mishap with a crew of people he was with while leaving a private house party just hours later.

No word on what exactly he was saying -- but it sure reads like ... "LOOK WHAT HAPPENED TO MY F***ING CAR!!!" This new angle also appears to show the bumper is slightly dented.

Like we said ... it should be easy enough to fix it -- but considering how damn pricey these cars are -- it might end up costing CB a pretty penny ... assuming insurance doesn't just handle it. In any case ... Chris wasn't happy about having to deal with it, period.

Drive safe, y'all.
