Ronda Rousey blows up on Kayla Harrison in brutal response to UFC champ: 'Who the f*** are you?'

Ronda Rousey already has her hands full with Gina Carano ahead of the pair's dual returns to MMA atop Netflix's May 16 mega-event. But at Wednesday's pre-fight press conference in New York, Rousey also sent verbal heat-seeking missiles toward the sitting UFC bantamweight champion, Kayla Harrison. In a recent interview on Jorge Masvidal's "Death Row MMA" podcast, Harrison reacted to a story Rousey told from their judo pasts about one of their "king of the hill" style training sessions.

The sessions consisted of testing a single judoka for as long as they could, with the rest of the gym going at them for a set period. In Rousey's story, she claimed to take out all the women until a male judoka took her out after an hour of the session. Harrison labeled the story a "blatant f***ing lie," before mocking the concept of Rousey vs.

Carano and calling each woman irrelevant, given the hiatuses they've been on. Rousey, 39, erupted with an unexpectedly scathing response Wednesday. "Gina is so relevant that she's the whole reason that the 145-pound division even exists," Rousey told Uncrowned's Ariel Helwani.

"I am so relevant that the only reason [Harrison] has a job at the UFC is because of me. Kayla is so irrelevant that she couldn't even keep the 145-pound division around. Honestly, she's just sour because no matter what she does or what she accomplishes, she can't change the fact that she has the charisma of a wet towel and will always be in me and Gina's shadow.
