Ronda Rousey has a message for Kayla Harrison: "I'm trying to feed you. Stop biting my hand."

The former UFC bantamweight champion is opening up about what she calls a "complicated relationship" with fellow judo Olympian Harrison. It all started when Harrison dismissed Rousey's claim that her upcoming comeback fight against Gina Carano on May 16 is the biggest in women's MMA history. Harrison called Rousey "irrelevant," and the gloves came off.

But Rousey insists her intentions have always been good. "Me and Kayla have a kind of complicated relationship," Rousey explained on her YouTube channel. "She came to live in the same house I was in and train with us."

Rousey revealed that Harrison moved in with her training camp after a traumatic childhood. "She had been sexually abused by her coach for most of her life, starting at 8 to when it came out, and she was like 17. So she comes out, and she's just been failed by every single adult in her life and been severely traumatized by some real messed-up stuff."

Rousey, who won bronze at the 2008 Olympics in judo, faced Harrison twice in competition before the Games. Despite being older, Rousey won both matches. Harrison would go on to win gold in 2012 and 2016. "When she moved into the house, she was going through a straight-up mental health crisis," Rousey said. "I don't think anything that went down then ever deserves to be under public scrutiny. But when she was going through it, I unwillingly was going through it with her."

Despite the tension, Rousey says she still wants what's best for Harrison. "I wish her the absolute best in life and all of the success and all the things over there. I just don't want to be involved."

Rousey has taken several shots at the UFC in recent months, but she sees her fight with Carano as a game-changer for women's MMA—especially for Harrison. "She's coming and talking trash about me and Gina. I'm like, 'Dude, we're doing nothing but help you. We've done nothing but help you.' I literally have a vested interest in developing the heavier divisions."

With Harrison reportedly struggling to make weight in her current division, Rousey sees an opportunity. "She says she can't make weight in her division anymore. It's taken years off of her life. Help me help you. Who do you think would promote you at 145? Me. Who do you think would help you get paid? Me. Who do you think is helping you get paid more in the UFC now because you have someone to give you a competing offer?"

For Rousey, the message is simple: this fight isn't just about her comeback—it's about building a future for women's combat sports. And she wants Harrison to get on board.
