Baby heart beat gender?

🌙 • 💙Emmett Poels💙🍼👶🏻 heart stolen by Brayden Poels💕👪
I was told that sometimes if the baby's heart beat is 160 or over its a girl but I also know my friends baby was a boy an his heart was 160, I was wondering how many people had a heart beat 160 for a boy or thought it was a girl then turn out to be a boy! Thanks ☺️ it was my first time hearing the heart beat for the 2nd trimester ☺️ 
UPDATE💢 ITS A BOY💙 heart rate was 157💙 the day I found out;
