What is wrong with my manager?

Ever since I started this job this girl is trying to make everyone like her more? She literally try’s to get close to every male new coworker that’s cool with me and she starts sticking her butt out for attention. There was a new girl coworker who started to get close to me she even try’s to cut our conversation like a weirdo? She starts feeling a way when people give me compliments on how I dress etc … the other manager made a joke about my man is here which was the bartender name Ben she even try’s sticking her butt out and doing the most for his attention and feels a way when he’s talking and laughing with. Everyone talks about how independent and hardworking I am.. she starts talking she’s independent and hardworking too? Like why is this person competing me?
