Madison posted a slideshow of photos in which she and Grant were posing and kissing in a classic white convertible, and she captioned it, "27 days."
This past weekend, the Season 24 The Bachelor alum and Grant, a 26-year-old Missouri-based speaker and aspiring pastor, celebrated their love and upcoming nuptials with an engagement party in Dallas, TX.
Madison and Grant -- the son of billionaire Kenny Troutt, who founded Excel Communications and owns a thoroughbred horse farm, according toUs Weekly -- celebrated with family and friends.
Madison posted photos from the event on Instagram and wrote, "You and me forever."
She and Grant struck poses in front of a giant balloon wall as well as a sign that read, "G & M."
Grant proposed marriage to Madison and the couple got engaged at The Breakers Hotel in Palm Beach, FL, on July 31 after eight months of dating.
"Some people think [eight months is] short, but you know, honestly, when you know you know," Madison said in a joint interview with Grant via Amazon Live in August.
"And something that we have made a commitment to do is to pursue purity and to wait until marriage [to have sex], and so because of that, we're not trying to have a super long engagement."
Grant joked, "Let's wrap this up! Let's wrap this up!"
"How quickly can we go?!" Madison added with a laugh.

But Grant explained on a serious note, "It's hard. It's not easy... But we believe it's worth it and God designed that to be so beautiful in marriage. So that's what we're waiting for!"
Madison told People in August of her upcoming wedding, "We want the wedding to embody our values and beliefs and be the best celebration with all of our people. We want a chic and classy wedding... We are so excited to do life together!"
Going back to when Grant and Madison first met, Grant, a former basketball player who suffered an injury that sidelined him in college, said he saw a picture of Madison after her The Bachelor stint and called her his "dream girl" -- but then nothing happened for six months.
A mutual friend named JD then set Grant and Madison up on a date, although both individuals were a little reluctant at the time and thought the timing wasn't the best.
Grant -- who had been single since 2015 -- said he called Madison up on November 24, 2021 and asked her out on a blind date, and then he met her for the first time on December 3.
"I was overwhelmed with nerves," Grant admitted, adding how he had never seen such a confident and beautiful woman who's also a "dreamer."
The pair's first date was at a Mexican restaurant in Dallas, and Grant called their conversation "electric" and "inspiring" that night.
While the conversation was effortless and apparently blew Madison away, Madison said she still needed proof that Grant also had some "swag" and could jam out to Justin Bieber or Drake and just "chill and vibe" with her.
After dinner, Grant, without being prompted, put Drake on the radio in his car and suggested the pair drive around downtown just for fun, which made Madison swoon. She said Grant seemed "so special" at dinner but that car ride "sealed the deal" for her.
"I was like, 'Do you want to just get married right now?'" Madison said of their first date.
Once Madison returned home, she told her mother that night that she was in "trouble" and she thought Grant was "The One," which was something she had never said before.
Madison debuted Grant on Instagram in May, writing, "So now y'all know, I got the realist G in town. Grant Michael Troutt, so full of passion and purpose and joy, I am proud I get to do life with someone who loves Jesus and people like you do."
"The past 5 months have been the best and wildest adventure," the proud Christian and virgin continued at the time.
"Full of highs and lows but there's nobody else in the world I'd rather do life with... You are my best friend. My favorite hello. My hardest goodbye. There's nobody else in the world like you. Let's keep dreaming, vibing, serving, and loving. G&M."
In fact, Madison had already turned down a stint on Bachelor in Paradise's seventh season, which aired in Summer 2021, by that point.
"I didn't feel like Paradise was really my scene. Some of my friends went on there and had a great time, so good for them! But it just wasn't my thing," the Alabama native shared last year.
Madison wasn't even sure if starring onThe Bachelorette would interest her, as she said it wasn't on her "radar" at the time and "a lot of conversations" would need to be had for her to consider it.
"I would have to feel pretty confident of what I would be stepping into and also feel like it was where God was leading me," Madison said.
On The Bachelor's 24th season, Madison seemed to be Peter's frontrunner and top pick, but she quit the competition during her final one-on-one date with the pilot. Madison seemed torn up over the fact Peter had been intimate with one or more of his other finalists.
Peter and Madison also constantly questioned if their relationship could make it long-term due to their different lifestyles and motivations.
Peter's mother Barbara Weber claimed Peter loves to party and is generally "spiritual," but Madison claimed to have devoted her life to God. She even graduated seminary school and had envisioned herself becoming a pastor's wife.
Not only was Madison a virgin on the show -- and Peter had sex with Hannah Brown four times in the Fantasy Suite on The Bachelorette's fifteenth season -- but Madison said one of her biggest goals in life is to open an orphanage.
Madison also said she expected her future husband to be the religious leader of her future children, and Peter admitted to the bachelorette his faith could definitely be stronger.
Peter therefore proposed marriage to his last remaining bachelorette and technical winner, Hannah Ann Sluss, but then he called off his engagement to Hannah and asked Madison for a second chance.
Madison agreed to try again, but just two short days after Peter and Madison's joint appearance onThe Bachelorseason's After the Final Rose special in March 2020, the pair released separate statements via Instagram announcing they had decided to split and end their revived romance.
Madison told Us Weekly in October 2021 that she and Peter no longer spoke and had not been in communication at all. After dating Peter, Madison lived in Dallas and entered a relationship with another man that only lasted about eight months.
