Three days after news emerged that the Bachelor in Paradise stars were engaged, Dean confirmed their next chapter by sharing a carousel of pictures from the moment he got down on one knee and popped the question to his future wife.
"Under promise," he captioned the Oct. 27 post of the two on the beach on the Kauai Island of Hawaii. "Over deliver. 10.24.22."
Caelynn also shared the romantic images in her own Instagram post, writing, "The hardest and scariest hike I've ever done led to the best day of my life. I can't wait to be velcroed to you forever."
Dean and Caelynn received lots of love from Bachelor Nation in the comments section of his post, including former Bachelor in Paradise winner Raven Gates, who wrote, "This brought a tear to my eye!!! I'm so happy for you both."
Kendall Long added, "Makes my heart happy! Congrats you two." Meanwhile, Becca Tilley also sent her best wishes, writing, "This is perfect!!!!!!! The joy in the photos! Ahh!!!! So happy for y'all!!!!!!!"
Dean and Caelynn began dating in 2019 after meeting on the ABC reality show. At the time, a source told E! News that the former Bachelor star traveled to Spain to meet the former Bachelorette contestant, with the two spending four days together before traveling to Italy and then back to Los Angeles.
Earlier this month, Dean shared details about his proposal, revealing that he had actually lost the 4.5-carat emerald-cut diamond ring that he planned to give Caelynn. However, he was able to get a placeholder ring to give her until he found the original piece of jewelry.
"It might be in the garage somewhere," he noted during the Oct. 23 episode of his Help! I Suck at Dating podcast, "but moral of the story is don't put your engagement rings in the junk drawer."
He also hinted that the proposal would happen soon, saying, "It'll happen by the time this podcast airs. Maybe. Maybe the day after it airs."
