My daughter is boy crazy!

Help! So my 12 year old daughter is not close to her dad. In 6th grade this last school year. I found that she was getting to know a boy. I was fine with it, but I told her I didn’t appreciate her being sneaky about it and having inappropriate conversations with him. Well recently, my friend went through her daughters iPad and found videos of my daughter and her daughter twerking and shaking everything they have, showing inappropriate cleavage, dancing seductively, middle fingers, just a whole lot of mess. So I went though my child’s phone and I’m so let down. She is really hungry and desperate for male attention. They made a middle school “gossip” page and she ended up on there as the most “passed around”

She told her friend that she bets she will “pull a new kid on the first day of school in 7th grade”

And just is never ok being “single”

So I took her phone not bcus she’s talking to ppl but she’s not respecting herself. Bcus her grades dropped in 6th grade. Bcus she dropped all her hobbies. The gossiping, the talking about ppl, the worrying about boys, etc. we agreed she will be in a new school. I know she will like boys wherever she goes but my plan is to get her to stay busy enough so that she focuses on herself. I want her to like herself to listen to herself, get to know herself again. I just don’t know what to do!
