DWAYNE "THE ROCK" JOHNSON is one of the coolest celebrities ever . . . and it's because he's always doing things like this . . .
A 19-year-old man named Angelo Pizarro lost his mom and his sister in a car crash, and his mom was a huge fan of The Rock. So the guy started a social media campaign to get The Rock to give her a shout-out for the funeral . . . and he came through.
He said, quote, "I'm sending you so much love and light and strength your way from my family to yours . . . I'm so sorry to hear about your sister and your mom . . . Stay strong."
Angelo replied, quote, "I can't stop smiling knowing she's smiling so much. Just, thank you."
