UPDATE: Check out who won the title of "Most Shocking Split" here.
PREVIOUSLY: We've tallied the numbers and it's game on for the final two ex-couples in HuffPost Celebrity's "Most Shocking Splits" tournament.
If your NCAA bracket isn't faring so well, try your hand at ours. We started with 16 celebrity couples, all vying for top honors as the pair to shock us most when it came to the news that they were parting ways. Kim Kardashian and Kris Humphries were knocked out in round one (apparently a 72-day union doesn't even count as a marriage in our readers' books), and even Brad Pitt and Jennifer Aniston's infamous five-year marriage wasn't enough to send them to round three.
So who's still in the game? It's Heidi Klum and Seal vs. Courteney Cox and David Arquette. Klum and Seal advanced to the final round, beating out Arnold Schwarzenegger and Maria Shriver's scandal-fueled split by a margin of only 3 percent. Cox and Arquette had 64 percent of our readers' votes, knocking Jennifer Lopez and Marc Anthony out of the tournament.
Check back Thursday, March 29, to see which ex-couple will take home (to their separate abodes, of course) the title.
