Say what you want about his antics, but Justin Bieber is there for his friends when it counts, reportedly rushing to the aid of Floyd Mayweather Jr.'s three children after they were in a bad car accident in L.A. yesterday, June 29.

According to TMZ, the boxing champ was walking the red carpet at the 2014 BET Awards when he heard that his three kids were involved in a crash. He was apparently on the phone with Bieber at the time, who immediately sprang into action and raced over to the scene of the accident to check on Mayweather's kids, allegedly telling cops that he was a friend of the family and came to see how the children were doing.

Fortunately, despite the fact the accident was a multi-car collision, the kids were okay. He reportedly played them some of his new music to calm them down and was allowed to take them in his SUV and transport them to their dad.

Not only is Bieber close with Mayweather, he is also tight with his kids, particularly 14-year-old Iyanna. Last month, the Biebs shared a sweet photo with Iyanna on Instagram and  even made an appearance at her 13th birthday party the year before.
