While VERY VERY nice, still VERY VERY odd.

Last week, a 29-year-old paparazzi photographer named Chris Guerra was hit by a car and killed while trying to shoot video of JUSTIN BIEBER being pulled over in his Ferrari.

Now, CHARLIE SHEEN is donating $12,000 to cover Guerra's funeral expenses.  He says, quote, "A tragic incident like this erases the line between the photographer and the subject. 

This is just the latest in a long line of good deeds by Charlie:

1:  Last July, he announced that he was giving one percent of the profits from his new show "Anger Management" to the USO.  That guaranteed them a donation of AT LEAST $1 MILLION.

2:  He gave away the $250,000 he was paid for his cameo in "Scary Movie 5".  ($100,000 of it went to LINDSAY LOHAN to help her pay off her back taxes.)  The rest went to different charities.

3:  Last month, Charlie and his stunt double gave $100,000 to a 10-year-old girl who's battling cancer.

Come on...Sweet, cute little Justin Bieber wouldn't beat someone up!!

JUSTIN  is being sued by an ex-bodyguard for doing just that!

The guys name is Moshe Benabou, and worked for Justin from March of 2011 to October of 2012.  And he claims Justin was ABUSIVE.  During one incident, he claims Justin berated him and punched him in the chest multiple times.

He's seeking unspecified damages for assault and battery plus $420,000 in unpaid overtime.

Moshe was actually fired - apparently for being a pretty habitual liar.  He even lied to get the job in the first place by falsely claiming he had previously worked with JUSTIN TIMBERLAKE.
