Our company hired a coworker which is utterly unqualified, lied on their cv and does not grasps even the basic despite somehow possessing a bachelors degree. I utterly despise her for her work ethics since she ties down at least one person to 'support' her during the day. Despite her clear lack of skills / experience she is very egoistic and always tries to put the spotlight on herself. 

Her attitude does not affect our professional "working"-relationship but as soon as me and my colleague are on lunch break I try everything to exclude her from anything we do and my colleague shares the same mindset.

For some reason she seems to target only me and my colleague as her potential lunch break "friends".

Up until now I had to bluntly tell her twice that and why she is not welcome and she started crying and throwing a tantrum afterwards.

AITA for excluding her?
