See wedding of Penn’s Bachelorette in prime time Sunday

Sunday at 9, in the time slot that usually features Once Upon a Time, Disney's ABC will feature one of the few Bachelor or Bachelorette romances that has turned out like a fairy tale.

The bride, Ashley Hebert, was a University of Pennsylvania dental student during her gig as Bachelorette No. 7 last year. She currently is a first-year resident in pediatric dentistry at St. Christopher's Hospital for Children in Philadelphia.

The groom was guy who got the final rose that summer - J.P. Rosenbaum, a New York City construction manager.

Actually, the Princeton residents are already husband and wife, hitched Dec. 1 during filmed ceremonies at a Pasadena, Calif., hotel.

Only one other such match - Season 1's Trista Rehn and Ryan Sutter, who also said prime-time "I do's" - proved lasting. Other ended in heartbreak, even accusatory tabloid fodder.

Hebert's stint on the show wasn't easy - and it almost didn't happen.

A friend told Hebert about a casting call for The Bachelor in Philadelphia, and "I figured, what the heck?" she told The Inquirer's David Hiltbrand last year.

She got chosen for the show, which debuted in January 2011, but didn't win the heart of returning Texas winemaker Brad Womack. Her third-place finish, though, was for an invite to experience The Bachelorette's emotional roller-coaster ride that spring.

The trusting young woman from a small town in Maine got blindsided by one louse, roasted callously at a comedy club, and later endured having her supposedly passive personality dissected on social media.

"America's Wounded Sweetheart," Hiltbrand dubbed her, but suggesting editing may have exaggerated her insecurities.

On the final show, filmed in Fiji, Ashley had two smitten dudes, with her older sister clearly favoring with winemaker Ben Flajnik, which prompted Hebert to call her the b-word. Both guys proposed. J.P. got a yes. A crushed Ben became the next Bachelor, only to choose a woman who seemed to backstab other women on the show, and afterward reportedly dumped him for another Bachelorette reject.
