Snoop Dogg came to the rescue of a stranded driver who had broken down on a California freeway on Sunday.

The 'Drop It Like It's Hot' hitmaker aided Katrina Graham when her car broke down on the freeway in Riverside, California, when she was driving back from church.

Katrina told TMZ that, as she waited for her brother to come to help her out, she heard a knock on the window and when she turned to look, saw Snoop looking concernedly at her.

He offered to give the stranded motorist's car a push because he thought she was in an unsafe spot, and parked his own car off the exit before running back to help her out of the way of moving traffic.

The 46-year-old rapper then found the time to pose for a picture with Katrina, before heading back to his own car and driving off to the NBA All-Star Game.
