The 21-year-old "What Do You Mean?" hitmaker and his crew passed a woman shouting in the street and decided to comfort her, reported Aceshowbiz.
They quickly pulled over to see what was going on and Bieber personally helped the woman to get up and escorted her to the street curb before consoling her.
The singer also acted heroically in 2014 when Floyd Mayweather Jr 's kids got involved in a car accident. He rushed to the scene to console the children.
