Ronda Rousey and Kayla Harrison come from the world of judo, and with the latter about to fight for a title, we asked her opp, UFC Bantamweight champ Julianna Pena, about all the comparisons to Rowdy!
TMZ Sports spoke with the champ just days before the Octagon door closes behind Pena and Harrison in the UFC 316 co-main event in the Garden State ... and let's just say Julianna doesn't see the similarities between Kayla and Ronda.
"Ronda was such a phenom in the fact she was just able to take everybody out in 10 seconds or less," the Venezuelan Vixen said.
