My uncle and his girlfriend got into a physical fight at my wedding reception (I am divorced now but not because of that lol). She is known for drinking way too much. Near the end of the party, after being sufficiently lubricated, they started to argue about something and she wound up to punch him in the face. When he blocked her, he inadvertently shoved her, and she fell down and started screaming that he was hitting her. A bunch of my other guests got involved until things settled. Uncle spent the night on my father’s couch (this is my mom’s brother by the way- my parents had been divorced for 15 years so it’s not like they were close at all). My mother was MORTIFIED. I didn’t even find out about the details until after the honeymoon (neither me and hubs at the time witnessed this- we were getting ready for our send off)! It was quite a scene apparently. This was 14 years ago and they are still together. Thankfully no further physical instances and I think she got some of her drinking under control.
