Breaking up is hard to do -- especially when you are doing it in the public spotlight.
Though there's no official split confirmation when it comes to Robert Pattinson and Kristen Stewart's troubled relationship, things aren't looking good. Since news broke last month that Stewart had cheated on Pattinson after years of dating, it seems like things are (obviously) not going well between the pair.
Many rumors have been floating around about what's going on with KStew & RPatz, but one thing is for sure: The drama surrounding them isn't going to end anytime soon.
Of course, Pattinson and Stewart wouldn't be the first famous couple to have a messy, headline-making split. Perhaps they can get some pointers on what not to do from those who have been in their shoes -- and on the covers of those celebrity magazines.
