Married friend not acting married?

I'm 22 and so is my married friend. Shes been married since she was 18 and her husband is in the marines. He signed up shortly after getting married against her wishes. I think she got married too young and is now trying to party. Her husband is currently at a base in another state. I have a lot of guy friends that I hang out with. When we go out my friend drinks only a few drinks and says shes trashed and gets all over the guys we are with. She gives them lap dances, and says nasty things to them, and dances inappropriately on them. She even exchanges numbers with them. She says her husband doesn't care what she does bc he knows she won't do anything. I know all she wants is the attention but its getting annoying. We can't go out with anyone anymore without her being all over them. She even asked me if I was interested in one of the guys and thats the one she likes to be all over the most. I even suggested not hanging out with them anymore but theres one guy she wants to continue hanging out with. I don't know how to tell her its getting annoying or tell her that what she does is inappropriate without her getting upset at me.
