There are multiple reasons why I know this is bullshit, OP - my girlfriend is way into makeup as a hobby. First, those palettes are expensive as fuck and there is no way she'd leave it open laying out like that. Second, that beauty blender doesn't look like it's been used since it was cleaned last. Third, that bottle of foundation is probably expensive and if not stored in a makeup bag, would at least be standing upright somewhere. Fourth, there is no eye makeup here - this is literally just liquid foundation and a foundation palette; if she's got liquid foundation she applies with a beauty blender she probably throws some shit on her eyes too. Fifth, as has been pointed out there is no reason she would do her makeup at your desk and not a bathroom mirror.
