The biggest rollercoaster relationship of 2009 has got to be that of Jon and Kate Gosselin. Their family of ten rocketed to reality show fame with the TLC show Jon & Kate Plus 8, but the pair called it quits just before their 10-year anniversary. Following rumors of Jon's alleged cheating, the couple officially filed for divorce in June. Countless legal battles between Kate and Jon -- and Jon and TLC! -- ensued with Kate eventually getting custody of the eight Gosselin kids. But in a last-minute act of chivalry, Jon brought roses to the courthouse for his soon-to-be-ex-wife -- which she happened to leave behind when she exited the building. The Gosselins are set to be legally divorced by the end of the year.
