Baby daddys girlfriend said if she cant be at the hospital then he wont be either

So my baby daddys girlfriend, told his mother that "If I cant be in the hospital room when shes giving birth then I won't let him be there."

Should I even address it or leave it be?

I'm about 32 weeks pregnant, and don't want the stress but it upsets me.

Am I wrong for not wanting her in the room while I give birth?

I told her it was fine for her to come see the baby, but I feel as if me giving birth is a little personal and I don't feel comfortable with her in the room.
