Question about how to deal with my friend?

Okay I need some advice here. One of my really good friends is absolutely obsessed with having a girl. Last year we were pregnant together and the moment we found out she said “oh I know you are having a boy and mines a girl” and she just kept going on and on about hers being a girl and at her 20 week ultrasound she found out she was having a boy and she was in denial for really long time. Now I am pregnant with my second baby and I am still really early and do not know the gender and I don’t care what I have as long as the baby is healthy and we went out to lunch and she goes “oh well I know this is a boy and kind of laughed and then she went on to say “oh and we are trying for another and it’s going to be a girl. I just do not know how to deal with her, I just don’t see why it’s such a priority for her to tell me what I’m having or constantly empower herself? I do not want to hurt her feelings but this kind of stuff just rubs me the wrong way.
