EXCLUSIVE: Moments after Brad Womack proposed to Emily Maynard on last night's 'Bachelor' finale, millions of fans were shocked to learn that the couple have already gone through a breakup, and while Brad told viewers he was ready for marriage, sources tell me the couple has since broken up for good.

"Emily is so insecure, she just isn't cut out for all the fame and attention her relationship is under," a show insider tells me. "The six weeks of shooting the show in paradise was easy, away from prying eyes and photographers, but since they both returned to their normal lives things have been a disaster."
