Prayers and advise

Hi everyone, I am in need of some guidance. Our adult daughter is not following Jesus right now and has developed quite a fowl vocabulary which is so shocking to me as it was not something she grew up with but I know that their friends are bad influences in this area. One thing that has really become quite offensive to me is when she will say "Jesus" or "Oh my God", it has really brought me to tears at night just thinking about it and just her walk with God. I feel like I need to say something to her but she is an adult and I pray for her constantly for God to intervene in her life. However is it inappropriate for me to ask her not to say it in our home? She always says it but catches herself because she knows how we feel about it. I'm so hurt.
