How to motivate the “mean girl”?

One of my MS students struggles terribly with comprehension of class material and using academic language in general. Her testing scores in ELA are very low and I do believe she would benefit from language therapy. The issue is, she despises speech therapy and will not apply herself unless there is someone to impress (i.e. boys she likes). I have had to move her from several groups due to bullying others over the past two years. She is very focused on her popularity and will not interact with me in the classroom. We have made improvements in participation and she doesn’t flat out refuse to attend speech during pull out buts it’s more like she’s doing the bare minimum so she doesn’t get in trouble. I know the material during therapy is relevant to what is being discussed in the classroom and the other students have no issue engaging with the content. It’s obvious she does not give AF and her teachers agree. Teachers and I can’t seem to figure out the best model of services for this student when she needs such a high level of support.
