The 28-year-old Maine native got hitched over the weekend in Pasadena, Calif., to 35-year-old New York resident J.P. Rosenbaum, who proposed to her on the seventh season of the ABC dating reality show "The Bachelorette." Hebert tweeted "12/1/12 goes down in history as the best day" of her life.
A spokeswoman for show producer Warner Bros. Television says the wedding will be aired Dec. 16 on ABC.
Hebert also competed on the 15th season of "The Bachelor." She grew up in Madawaska, Maine, and is a dentist. The couple lives in the New York City area.
Only one other couple that became engaged on the TV show's finale has married. Bachelorette Trista Rehn married Vail, Colo., firefighter Ryan Sutter in 2003.
