Who's in the wrong here my friend or his divorced recently dating dad?

I have a friend who's turning 20 soon. She lives with her dad as their parents have divorced recently recently and he started seeing a woman his daughter age who is 19 or 20. Her dad is 47 and she saw her at their house and told her dad off for having sex buddies her own age and yelled at them. Her dad kicked her out of the house and she lives with her mom now.

I personally think it's none of her business but I didn't tell her that.

Daughter is in the wrong
Dad is in the wrong
Both are in the wrong
