A married couple and their relative cheated death after they were almost trampled by a marauding bison at scenic Yellowstone National Park,  and  Breaking Celebrity News  has the video of the terrifying incident.  

Cathy Hayes - a teacher from Utah - was videotaping the huge beast at the park in Wyoming while her husband Jeff and his brother Donald watched-on.

But then the bison became agitated and charged her and her brother-in-law while her husband honked his car horn.

On CBS's The Early Show on Friday, Cathy told co-anchor Chris Wragge the bison "flipped me end-over-end like a rag doll, in the air."

It turned out she didn't suffer life-threatening injuries, but was pretty badly banged up - suffering severe bruises on her legs and knee.

Her brother-in-law, Donald, broke his shoulder when he tripped and fell.

Hayes revealed she could hear the bison stomping and snorting around her, and thought she was going to die.
