• 1. Mary Boleyn & Anne Boleyn

  

  This rivalry involves both a man and a throne. Mary took up with the King as his mistress yet Anne took the long-view at revenge and played coy until he broke away from the Catholic Church, had his wife executed and married her. No big deal.

• 2. Hillary Clinton & Sarah Palin

  

  One says universal health care, one says you betchya. It was never going to work out.

• 3. Foxy Brown & Lil Kim

  

  Foxy Brown accused her former friend, Lil Kim, of imitating her style spawned years worth of public dissing and all-round hip hop drama.

• 4. Jennifer Aniston & Angelina Jolie

  

  This one is pretty traditional case: Angelina stole Jen's man, Brad Pitt. Despite the fact that this happening years ago, it seems every other week they're on the cover of a new tabloid exchanging perfectly glossed sneers.

• 5. Rosie O'Donnell & Elizabeth Hasselback

  

  Dang these girls like to yell at eachother. If only it was about anything we cared about. This rivalry got so screamy that Rosie eventually left her spot on The View.

• 6. Serena & Blair

  

  This fictional, but no less delicious, rivalry is of the frenemy variety. Serena, the reformed bad girl, never ceases to irk her WASPy over-achieveing counterpart, Blair. High priced drama ensues.
