Csincsak and Lueders, a former thirteenth-season The Bachelor bachelorette who is four-months pregnant with the couple's first child, were married in a ceremony at the Rumor Hotel in Las Vegas, NV.
"I've waited for this moment my whole life," Csincsak toldPeople on Friday. "I tell her every day, she's the best thing that's ever happened to me. We just have fun together. We are just enjoying our time together and it doesn't matter what we do."
Lueders, a 28-year-old former flight attendant from Phoenix, AZ, was one of the 25 bachelorettes who appeared on Jason Mesnick's The Bachelor edition in 2008. Mesnick -- who had previously competed with Csincsak for Pappas' heart on The Bachelorette's fourth season -- eliminated Lueders on the first night during the Rose Ceremony which followed the season's initial cocktail party.
Several former The Bachelor and The Bachelorette participants were guests at the wedding ceremony, according to People -- including Mesnick and new wife Molly Malaney (who had included Csincsak and Lueders on the guest list for their own wedding earlier this year) and fourteenth-season The Bachelor winner Vienna Girardi.
"I'm ecstatic," Mesnick told People. "Jesse and I have this weird history because two years ago when we were doing The Bachelorette, we said we were going to be there for each other no matter what. At the time we thought it was going to be somebody else, obviously. In a small, strange way he ends up marrying someone from my Bachelor season, and it's just come full circle."
Csincsak and Lueders plan to honeymoon at "a secret location," according to Csincsak.
"Then we're going to go back to Colorado, pick up our two Siberian Huskies and start our life in Colorado," he told People.
Lueders and Csincsak -- who split with Pappas in November 2008 and then dated twelfth-season The Bachelorette bachelorette Holly Durst afterwards -- met when they both attended a Bachelor/Bachelorette reunion cruise to Mexico last year.
Ironically, Pappas and Durst both also recently got engaged.
