From Becca Kufrin to Serena Pitt: All the Bachelor Nation Stars at Abigail Heringer and Noah Erb’s Wedding! (Exclusive)

Abigail Heringer and Noah Erb first met and fell in love on season 7 of Bachelor in Paradise — so it was only fitting that many of their former costars were present to witness them say “I do”!

Heringer and Erb, both 29, tied the knot on Monday, Oct. 7, at the Philbrook Museum of Art in Tulsa, Oklahoma. They welcomed 90 guests, including BIP family members Joe Amabile and Serena Pitt, Chelsea Vaughn, Serena Chew, Ivan Hall, Thomas Jacobs and Becca Kufrin, Chris Bukowski and Anna Redman, Demar Jackson, Blake Moynes and Zac Clark.

One of Erb’s 10 siblings, his twin brother Aaron — who was a contestant on the latest season of The Bachelorette — served as best man.

Wanting to keep their wedding as small as possible, the couple only invited those cast members they are closest to and see regularly.

“We only wanted the people we have had a consistent relationship with since the show,” Heringer tells PEOPLE. “So my best friend Chelsea [Vaughn], who lives in New York. Serena [Chew], who was also on my season. Serena Pitt, love her. Also Joe [Amabile] and Ivan [Hall].”

Heringer says having the BIP crew in the house on their big day was “so special” because many of them were there when the couple’s relationship began. The two had their first date on the premiere episode of their season of the ABC reality series, and while they broke things off toward the end of the season, they later reignited their romance off-screen after filming wrapped in September 2021.

“It was a full-circle moment to have our costars [at the wedding],” Heringer tells PEOPLE, adding that she and Erb have taken trips with a lot of them over the years.

“We’re hoping that with all these people [who came to the wedding], we can move into the next stage of life together,” Erb adds.

Kufrin and Jacobs — who also met during season 7 of BIP and later married, just weeks after welcoming a son together — even had a hand in making Erb and Heringer’s engagement happen. Erb popped the question in August 2023 at a beachfront house in La Jolla, Calif., and Jacobs pitched in with the planning and preparations.

“[Jacobs] helped me with the arrangements and setting everything up,” Erb told PEOPLE at the time. “The proposal was perfect and everything I wanted to incorporate to make it special and ours.” 

To pull off the surprise, Erb told Heringer that he had planned a farewell dinner with Kufrin and Jacobs. (At the time, the couple was just days away from moving to Erb’s home state of Oklahoma together.) Instead, Erb led Heringer to the rooftop, where he asked her to marry him as the sun was setting.

After celebrating their wedding ceremony on Monday and enjoying a plated dinner catered by Prossimo Ristorante at their reception, the newlyweds danced the night away with their Bachelor Nation friends and other guests. Then, they whisked away on a honeymoon to Jackson Hole, Wyoming, where they planned to “cozy up,” explore the gorgeous scenery together and “have chill nights” at their Airbnb.
