"We have a 1 in 400 trillion chance of being born, and we are 2 of ~8 billion people in this world. I can only thank God for bringing us together and promise to go on the adventure of a lifetime with you," Bennett, 39, captioned an Instagram video on Monday.
"Thank you for making me the luckiest man alive @emilykchen 6.30.22."
In the video, set to the song "Come Away with Me" by Norah Jones, Bennett and Emily hold hands and stroll on a ranch in Wyoming before Bennett twirls his future wife and kisses her.
"We took this video... at T.A. Mouton Barn on Antelope Flats in Moose, Wyoming a few days after the proposal and have been enjoying the last month together before sharing the news," Bennett announced.
The couple apparently got engaged in late June but decided to celebrate privately and cherish the moment until now.
Emily shared on her Instagram Stories how Bennett popped the question with a cushion-cut diamond ring and a proposal that made her cry.
Bennett revealed on June 20 that he and Emily were about to embark on their second road trip to Wyoming together.
"Last year we drove from NYC to Wyoming. It showed us we could handle stress, problem solve when [sh-t] hit the fan, not get bored of each other's conversation, have fun and enjoy nature, movement, cooking [and] camping," Bennett wrote.
"We enjoyed it so much we're going back! This time from LA to Arizona to Zion Natl Park to Jackson Hole to Beaver Creek, CO to Vegas and last stop in a tiny home in CA then back to LA."
Bennett first met Emily when he was a student in one of her yoga classes.
He shared in May of their relationship, "I never thought my first date after going on a reality tv show to find love would lead me to the love of my life. As it turns out, she was living five blocks away all along. Love finds you when you're least expecting it."
The wealth management consultant from New York City and Emily apparently began dating in Summer 2021 and kept their romance under wraps for a while.
"One year ago! Secret relationship @bennettandrewjordan," the Los Angeles-based yoga instructor wrote Monday on her Instagram Stories alongside a July 2021 throwback selfie with The Bachelorette alum.
Bennett and Emily went public with their romance in September of last year.
"Meet Emily @emchenyoga I'm pretty sure she's a real life [angel]," Bennett wrote on Instagram at the time, adding how he felt like the luckiest guy in the world to be dating her.
Bennett captioned a photo of Emily and himself striking a yoga pose and added, "Aside from being the most graceful yogi I've ever seen in my 15 years of practice, she has the best [heart] and spirit of anyone I've ever met."
And Emily thanked Bennett at the time for all of the "joy, play, positivity, and confidence" that he brought into her life.
"Meet Ben, the man that brings me indescribable happiness," Emily wrote on Instagram the same day Bennett had debuted their relationship. "Hope you don't mind seeing him here."
