A wild night and pregnant but who's the baby-daddy?

It was wild night teenagers were having fun and drinking, and partying pretty hard. This one girl named Serena ended up having sex with her boyfriend Darien but after that, she also fought with him and then, later on, later on, that night he left with some other girl, she got mad and so she drank herself even drunker and she ended up kissing some other guys at the party, she can't remember how many there were, but she thinks there were three guys tops that she dance with and flirted with and had some fun, but she couldn't remember their faces barely, the question is who did she get in bed with? Because that night seems to be a blur, and she doesn't remember? But the one thing that is clear a few months later she was pregnant.
