Well, one thing you can do is just ignore the fact that she's hates you. If she's still acting mad at you and you're not, that just shows whoever's at the audition that she can't work as well with other actors as you can. Plus, if she's really talentless, you won't need to worry. You can also take stageman's advice to practice, practice, practice, and remember- if someone doesn't like you and isn't nice, don't stoop to their level. Good luck!
