The selected suitor knelt on one knee and proposed to Hebert on a private Fiji island on May 13 during the show's taping, Life & Stylereported Wednesday.
"Ashley's elated," a source told Life & Style. "She's engaged to the winner and is wearing her engagement ring."
Another source told Life & Style that The Bachelorette couple is going strong after having been together for about a month since the show wrapped filming.
"She's definitely still in the relationship," the source said. "She says she's really happy."
While Hebert and the former bachelor are not allowed to publicly reveal their relationship until the show's finale airs in August, the 26-year-old dental student's alleged fiancee has apparently been raving about his wife-to-be privately.
"He said, 'I'm in such a great place in my life, and I'm the happiest I've ever been,'" an additional source told Life & Style.
