MMA fighter Ronda Rousey recently got herself a new job that — training her "Furious 7" co-star Vin Diesel's seven-year-old daughter Hania Riley Sinclair. Apparently, Rousey and Hania had been in Judo sessions together and Diesel reveals all the details.

In a recent interview with WENN media outlet, Diesel, with real name Mark Sinclair, shared how his seven-year-old daughter already received her orange belt in Judo with the help of her casual coach, the undefeated UFC Women's Bantamweight Champion Rousey.

"First of all, I feel sorry for anyone that has to [date my daughter]," Diesel said of Hania's latest undertaking. "I wouldn't want that on my worst enemy because I'm just that kind of dad. I've been thinking about this since the day I cut the umbilical cord, and because of that, I made a decision early on that I was going to do everything in my power to empower her to handle it herself."

Indeed, Hania may be able to handle herself in certain situations at her young age, especially since she is being trained by Rousey herself, the fighter and actress who apparently developed a close bond with Hania's father during their "Furious 7" filming days.

"Because of her 'auntie' Ronda Rousey, she is now an orange belt with stripes in judo. I'm dealing with it early. I'm creating a beast, and I want her to be able to say 'No means no,'" Diesel continued as quoted by WENN.

Rousey herself started training Judo at an early age, Bleacher Report says. Since then, the MMA fighter won a bronze medal at the Olympics had an undefeated title in the UFC.

However, Hania's casual trainer has also been quite active in her Hollywood career, which kicked off when she starred in the "Fast & the Furious" franchise with Diesel. Rousey also had roles in the new "Entourage" and "The Expendables 3" films.

Rousey is currently busy in training for her upcoming fight at the UFC 193 on Nov. 15 against Holly Holm. Bleacher Report further revealed that Rousey's upcoming bought is quite interesting from her past ones since Holm is also reportedly an excellent boxing star, but the fight could still be favorable for the undefeated fighter.

Diesel and partner Mexican model Paloma Jimenez have three children including Hania, younger brother Vincent and Pauline, who was named after Diesel's "Fast & Furious" co-star, the late Paul Walker, Star Pulse reports.
