Three months later after the marriage proposal, Swaggy, 23, and Bayleigh, 25, are moving into a raised ranch-style house together and planning their wedding.
On January 1, the Season 20 houseguests posted the same photo on Instagram of the couple posing together in front of their new house with a "sold" sign on the front lawn.
"Do not despise Humble beginnings, for the Lord rejoices to see the work begin. -Zechariah 4:10," Bayleigh captioned the cute picture.
"I'm excited to start the work. I take getting married and moving very seriously and I will not take this blessing for granted ! 2019 here we come."
And Swaggy captioned the image on his profile, "Ohhhh welcome to the Swayleigh house. Bought our first house together. January 1st, 2019. New beginnings. 2019 is gonna be an excellent year. WE ARE LIT MAN GANG!"
"I got my man cave downstairs, she has her Yoga Studio in the house, we got a YouTube room, backyard kinda' big .. Swayleigh. Happy New Year ladies and gentlemen," he continued.
"Hope your year is gonna be as good as mine. God, continue taking over my life! Open to receiving all blessings. And for you Bayleigh, let's continue making things happen. #SwayleighSOLD."
And Bayleigh told ET she was "still in shock" over how life unfolded following their Big Brother stint.
"Like, princess fairy tale, all of that -- he does everything that I want him to do, so it's good," Bayleigh noted.
The happy couple said they are hoping to marry in September 2019, and Bayleigh revealed she would like their wedding to be a big and colorful event, complete with great music, a large guest list and a very dramatic wedding dress.
But the past several months haven't exactly been perfect for Bayleigh and Swaggy.
After Bayleigh was evicted from Big Brother, she sadly suffered a miscarriage while in the jury house. (The pair, however, did not announce the miscarriage until late September).
"I went through the most traumatic experience in the house. Obviously losing a baby was traumatic, but the fact that I told him I was having a baby and he didn't run from me -- he was immediately like, 'Alright, I'm full support. What do you need? Are you okay?' -- like, freaking out," Bayleigh recalled.
"The producers were like, 'All he does is call and ask about you.' And I was like, 'He's the one! He loves me.' So, yeah. He's just been my rock. I can't live without that."
In a separate interview withUs Weekly, Bayleigh and Swaggy admitted they are in no rush to welcome children, but when they are ready to start a family, Bayleigh would like an even number -- either two or four kids.
Celebrity Big Brother is set to return to CBS with its second season on Monday, January 21 at 8PM ET/PT.
