Is expired bottled lemon juice safe to drink?

quinn

My mom bought a big bottle of lemon juice for me to make a drink I have been waiting forever to make. The bottle said it expired 06/09/17. So roughly 3 months ago. Is it okay to make my drink still? I read online that some people say it is completely fine since it is an acid, but others say it is dangerous because bacteria can grow quick. It has net been opened yet and my mom won't return it. Is it safe? Please respond ASAP
