It looks like Bachelor Bob is going to have the last laugh. Bob Guiney the portly jester whom Trista Rehn rejected on ABC's The Bachelorette has been chosen the next star of The Bachelor. Since getting the boot from Ms. Rehn last year, Guiney became a celeb in his own right, appearing on Oprah five times, signing a book deal and shedding 40 pounds in the process. And proof that he's not holding a grudge against his ex-crush, the 32-year-old mortgage broker has reportedly agreed to sing at Trista's wedding to Ryan Sutter an event ABC will air next fall as part of a four-hour special. And if all goes according to plan, the network hopes to broadcast the couple's divorce hearing at the onset of November sweeps.
