Annoying girl here at work!

There is this girl that just started here in the office about a month ago, that annoys the hell out of me! She is always asking me to use my stuff.. Personal stuff, not work related.. My hair spray, lotion, brush and today she wanted perfume! What the hell, bring a purse! Then she says things that are out of line all the time.. She told my room mate he looked like he had gained weight! lol That is so rude, you don't tell someone you hardly know something like that!
