"Ashley and J.P. will get married on TV, it's guaranteed," a former The Bachelor contestant toldLife & Style.
According to the Life & Style source, the wedding may follow scheduling similar to that of former The Bachelor couple Jason Mesnick and Molly Malaney's ceremony and air early next spring after Ben Flajnik's upcoming season of The Bachelor concludes.
"It will take place as early as next April after Flajnik [who was rejected during The Bachelorette's seventh-season finale when Hebert selected and presented her final rose to fellow suitor Rosenbaum, who then proposed, instead] has his season on The Bachelor," the source said.
Hebert and Rosenbaum would reportedly like to exchange vows in California or at a destination along the West Coast, a presumably pricey event that ABC will take care of.
"ABC is happy to pay for a wedding when it knows the couple are as happy and in love as Ashley and J.P. are," the source added.
The happy couple has apparently come a long way since August -- when Hebert moved into Rosenbaum's New York City apartment for a temporary fix until they could find a place of their own -- and Rosenbaum told Reality TV World he wasn't sure when a wedding would take place in their future together, nevermind whether the ceremony would be televised.
"Really, we haven't given any serious thought to it just because we do have so much going on with her finishing school and moving up here and finding a job and moving into a new place. There's just so much going on that we really haven't thought about it," Rosenbaum said.
"We're not going to wait five years to get married, but we're going to take it one step at a time and once we settle down, we're going to start talking about a wedding seriously. And as far as having it done on TV, we talk about it in jest sometimes, but no real thought has gone into it."
