Grodd, 27, and Faddoul, 26, made a special guest appearance in Mexico and exchanged vows on the second season of Bachelor in Paradise, the reality series on which they first met and fell in love, Us Weekly reported in its July 13 issue.
"They got married at the start of the show!" a source told Us of the couple who have been dating for just over a year.
Six days ago, Faddoul posted a photo on Instagram of a giant box of luxury red roses Grodd had sent her. She joked that red roses are "never ending" in their relationship.
Back in early January, Grodd and Faddoul talked to People at The Bachelor's Season 19 live red carpet event.
"[We] fall in love more every day," said Grodd, a sports medicine manager. "We're just really happy being able to be close to each other. We have been going to lots of different venues, and our wedding is planned for this year in 2015 -- hopefully in the summertime."
Faddoul, who owns an elderly care facility, added at the time that the exact date of their wedding had yet to be determined. However, she admitted they couldn't wait to start a family.
Grodd popped the question at the end of the one-month filming time forBachelor in Paradise. They got together once Grodd stole Faddoul away from Robert Graham, who thought he was hitting it off with Faddoul and really liked her at the time. The couple was inseparable ever since.
