Rousey's mom says she's related to one of North America's first black physicians

Ronda Rousey's mom just dropped a nugget on the former champion's heritage and it's pretty awesome.

TMZ caught Rousey in LA recently and asked the UFC superstar what was the last movie she'd seen. Rousey politely told the cameraman that she would prefer to continue spending time with her mother and sister than conduct an interview, but momma Rousey was more than happy to answer.

"'Before His Time.' It's about my grandfather, Ronda's great-grandfather. They show it during Black History Month every year in Canada because he was one of the first black physicians in North America," Dr. AnnMaria De Mars told TMZ.

The documentary covers the life of Dr. Alfred E. Waddell, a Trinidadian doctor who immigrated to Halifax, Canada, after laying down roots in New York. His bio on the White Pine Pictures (a Canadian production company), says this about Waddell:

Rousey and Dr. AnnMaria appear proud to be related to Waddell, and who wouldn't be?
