Pregnant friend took our baby name

I have a friend who is famous for copying me. She learned DH and I were TTC and she became pregnant. We were talking and she shared baby names that they had picked and I felt safe sharing ours since she seemed pretty set on their names. She found out last week the gender and long behold announced on FB and it is our boy name! I want to call her out but not sure how without the comeback of well you aren't pregnant.
