On Sunday, the happy couple took to Twitter to express their excitement for the nuptials. Hebert wrote, "12/1/12 goes down in history as the best day of my life!!" Her new husband added, "Who says fairytales can't come true!" The outdoor ceremony took place at the luxurious Langham Huntington Hotel, where "Bachelor" alumni including former "Bachelorette" stars Ali Fedotowsky, Emily Maynard and Jillian Harris, "Bachelor Pad" Season 2 winner Michael Stagliano as well as upcoming "Bachelor" Sean Lowe filled the seats. Meanwhile, Ashley Spivey, Hebert's close pal and former co-star during Brad Womack's second season on "The Bachelor", served as a bridesmaid. And the show's host, Chris Harrison, officiated the final rose ceremony of their lives. Hebert was looking forward to having members of "Bachelor" Nation present at the ceremony, as she shared her excitement about the big day with People magazine: "Today is all about our friends and family. It's about standing with J.P., looking around at all the people we love in the same room there to celebrate our love."

The 28-year-old dentist from Madawaska, Maine, walked down the aisle to a piano rendition of "Can't Help Falling in Love With You" by Elvis, and she met her soon-to-be husband under a chuppah in deference to Rosenbaum's Jewish heritage. Both Hebert and Rosenbaum's mothers took part in a Celtic knot ceremony, tying their children's wrists together before saying a prayer that brought many to tears. As the two finally celebrated their official announcement as husband and wife, guests threw up confetti and rose petals as the pair headed back down the aisle to kick off the reception. The nuptials of Hebert and her 35-year-old construction manager husband mark only the second time in the show's history where a couple that got engaged on the finale tied the knot. The inaugural "Bachelorette," Trista Sutter, married winner Ryan Sutter in 2003. They were the first couple to air a TV special of their wedding. In 2010, Season 13 "Bachelor" Jason Mesnick married Molly Mesnick, who was the runner-up to Melissa Rycroft. He famously dumped the recent "Dancing With the Stars" winner in favor of Molly, who is currently pregnant with their first child. Both couples were in attendance at the Rosenbaum wedding. The two-hour ABC special, "The Bachelorette: Ashley and J.P.'s Wedding" airs Sunday, Dec. 16, at 8 p.m. ET/PT on ABC.
