Pregnancy drama with my friend. Help/advice

My friend and I are having baby within days of each other. She’s due a couple days before me. My friend just so happen to be dating my boyfriends cousin. So we see each other at their family events n what not. Well my mil and his cousins mom have been in like a grandma competition. They constantly are going back and forth about what they buy for the babies (we’re both having girls). They even were causing drama about our baby showers because one of them copied the other or whatever. Me and my friend are irritated by it because it makes us uncomfortable. Our mils both planned drive thru showers for us, hers was last weekend and mine is this weekend. Our mils literally started talking about our sizes. Like she was a bigger girl before getting pregnant and has put on a good 50 pounds and got a little wider, well so shit she’s fucking pregnant!! I on the other hand have stayed pretty small, my belly isn’t huge and I haven’t gained really any extra weight, only 25 pounds. We’re almost 36 weeks pregnant. My mil was saying how my friend got so fat and her face is fat and basically saying she looked gross. She was telling my friends mil that I still “looked cute” and my friend didn’t. THIS WAS AT HER DRIVE THRU SHOWER. Now I feel uncomfortable because I don’t want my friend to look at me differently because she has struggled with her looks during pregnancy, she told me this. People telling me I’m so small isn’t necessarily a compliment but I couldn’t imagine hearing I looked fat and gross. Ugh. Should I say something to my friend? I don’t want this to turn into resentment toward me or problems with me and her but we’re both very aware of what’s going on and being said.

I may have been misunderstood, my friend already knows what has/is being said about her. I didn’t mean to tell her what they said about her being big but just let her know I don’t agree with any of this. I just want to clear the air with her and I
