The 'Fast and Furious' star has revealed the undefeated UFC fighter is working with his seven-year-old daughter Hania Riley on her judo and is "creating a beast".

He told WENN: "First of all, I feel sorry for anyone that has to [date my daughter]. 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.

"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.'"

And the 48-year-old star - who also has daughter Pauline, seven months, and son Vincent, five - recently revealed his daughter regularly sends him cute text messages since she became the proud owner of an iPhone.

He shared: "My 7-year-old daughter has an iPhone now. And she just texted me this, if I can read this to you.

"'Hi Daddy, I love you so much. I am so proud of you. I miss you so much. I believe in you, that you will make an awesome movie. I love you so much, I miss you so much. Love, Similche.'"
