Just mind your own business, do your work and do it well. That person's behavior only reflects poorly on him/her. If you conduct yourself professionally and do what's right, then your supervisors will see that situation for what it is. Tattling is not professional. Ridicule is not professional. Taking the high road is. Don't let that person drag you down, and don't play the game it will only come around to hurt you in the end.
If it's truly getting in the way of your work then tell the person directly "This is not working. When you behave this way it is creating a hostile work environment." Or something like that. If that doesn't work then take it to your boss but only after you have addressed the person directly with no results. Don't turn it into a complain fest, keep it geared towards how it is affecting productivity. Your boss doesn't want to hear about the petty little stuff.
