Do women really sometimes feel threatened by other women?

There’s a coworker who sucks up to the boss. She’s stunningly beautiful. She acts really cold and distant towards me. My mum said she might be feeling threatened by me, because I’m beautiful too and almost as pretty as she is. I’m Autistic, so it never occurred to me. Also, I don’t get jealous of other women. Does this actually happen?
