“Bachelor” host Chris Harrison is a single father with two kids, and he says he watches the show with his 12-year-old daughter to teach her about men and dating.

“It’s a great avenue for me to have a conversation with my daughter. As much as I’d love to lock her away, this is happening.” He asks her things like, “What do you think about how he treated her?” . . . and so far, he’s happy with how she’s responded.

Chris also has a 15-year-old son, and he was never interested in the show until recently, when he found out the girls he likes at school are into it.

Since Chris sees everything that happens on the “Bachelor” shows first-hand, it’s hard to imagine him wanting his daughter to do it. And he probably doesn’t.

He says he tells her, Remember, Daddy is watching at all times…I hear and see everything.”

But if his son wanted to do it? He says, “Have fun, buddy, go get ’em!” And yeah, he admitted it’s a total “double standard.”
