The youngster apparently thought Ruby was involved in a real fight with 5-year-old wrestling opponent Ryan, and charged over to save the day.

“It was so cute. The whole place was cracking up when it happened,” she added. “I only have boys, but if I had a daughter, I hope they would protect their sister like that.”
