MrBeast is known for his generosity when it comes to money. He's given away thousands of dollars in the past to wait staff, delivery drivers, homeless people, you name it. Well, he just did it again!

Now, she's joining RightThisMinute to tell us all about that crazy day and what she did with all that dough.
