Was today National Divorce Day or something? (No, April 16 is.) It sort of seemed like it was, though. Beyoncé's mom served her dad with divorce papers today. Ivana Trump filed to divorce Rossano Rubicondi this afternoon. LeAnn Rimes' husband served the country singer. And Jon and Kate Gosselin's divorce was finalized today, too. Elin Nordegren isn't there just yet, she's one step closer: Today she retained a lawyer to handle her divorce from Tiger Woods. Here's hoping your day wasn't nearly as eventful. [LAT, AP, People]
