The Bachelor alums packed the rows at Jade Roper and Tanner Tolbert's wedding, making for an exciting yet awkward reunion for the reality TV family.

Roper and Tolbert, who met and got engaged on Bachelor in Paradise's second season last summer, wed on January 24 in a beautiful "romantic" ceremony at the St. Regis Resort Monarch Beach in Dana Point, CA for The Bachelor at 20: A Celebration of Love special set to air Valentine's Day on ABC.

"I owe a lot to ABC," Tolbert told People with a laugh. "And to [my ex Kaitlyn Bristowe]. It's a weird chain reaction. A lot of Dominos had to fall to get us to this point."

Roper got emotional walking down the aisle, according to People, and her eyes stayed laser-focused on Tolbert, who couldn't take his eyes off her either. Tolbert reportedly told Roper in his vows that the worst times would be better with Roper than the best times without her. Singer Matt Nathanson also serenaded the couple for their ceremony.

Roper added, "There are people that I watched on TV, like [former Bachelorette Trista Rehn], and it's crazy that she's at my wedding!" 

The guest list included current The Bachelor star Ben Higgins, former Bachelorette Bristowe and fiance Shawn Booth, Rehn and husband Ryan Sutter, former Bachelorette Ashley Hebert and husband JP Rosenbaum with their son Fordham, former Bachelor Sean Lowe and pregnant wife Catherine Giudici, former Bachelor Jason Mesnick and wife Molly Malaney, former Bachelorette Desiree Hartsock and husband Chris Siegfried, former Bachelors Chris Soules, Andrew Firestone and Bob Guiney, and former Bachelorettes Andi Dorfman, Ali Fedotowsky, DeAnna Pappas, and Jillian Harris.

More former franchise contestants who made an appearance at Roper and Tolbert's nuptials were Nick Viall, Jared Haibon, Sarah Herron, Ashley Iaconetti and her sister Lauren Iaconetti, Juelia Kinney, JJ Lane, Michelle Money, and Ben Zorn.

Rehn, who also got married to Sutter for a television special, racked in over 26 million viewers. The couple reportedly talked to Roper and Tolbert about how the televised wedding can be "stressful" but they should "enjoy it and take it all in." Rehn and Sutter were also "honored" to have been invited.

Because so many people from The Bachelor family showed up, everyone basically had to run into ex-boyfriends or girlfriends.

"This is an incestual web of exes," joked Dorfman, who dated both Soules and Viall. "I don't really talk to any of them except for Chris, because he's right here!"

And Roper previously competed on Soules' edition of The Bachelor.

"I thought it would be weird," the Iowa farmer said of attending Roper's ceremony. "But it's not. This wedding makes me hopeful for love."

While Mesnick got to say hello to Jillian Harris from his season, Bristowe had to confront the most men of anybody -- Higgins, Viall, Haibon, Lane, Zorn, and the groom!

Higgins was the most popular man at the wedding, according to People, but he joked about how he didn't have a date. Higgins therefore playfully posed for photos alone. Lane also brought the jokes. During a toast, Lane reportedly told the crowd, "My mom had a crush on [Guiney] when she was a teenager."

The Bachelor alums all partied on the dance floor at the reception, during which Seal memorably performed "Kiss from a Rose" and "Every Time I'm With You." Viall danced with Money and Soules reportedly took the Iaconetti sisters around the dance floor. The bash finally died down around 3AM.

Fedotowsky and Stagliano couldn't drink because they're pregnant, but they apparently still had a blast. Former The Bachelor bachelorettes Erica Rose and Ashley Salter are also pregnant. 

"The cool part about this wedding is it's a lot of different people from different experiences coming together," Higgins told the magazine. "We're all here to honor love and that is a really incredible thing."
