My 'freind' thinks she is the hottest person ever but she is UGLY what can we do?

The whole diet tips thing is rude, but you can't do anything unless tou say what you just said on here to her face. I know it's annoying, but isn't it a good thing for a less attractive girl to have confidence? For the B.O. thing, buy her a perfume or something so you can tolerate her.
