You could try giving her constructive feedback (a longer response would be required to discuss what this might look like;) however, if she is being encouraged to show this behavior by the boss to “shake things up,” there may be little you can do to change her behavior.

The only behavior you can control in this situation is your own. I would advise you to take the high road, avoid making destructive comments or letting this person get under your skin.  I have seen examples like this in a number of organizations. Most often, they ultimately self destruct because of the competitive behavior. Just don’t let her take you down with her by getting involved in excessive competition. It can be frustrating, but it’s important to control your reactions.
