"Love is not found, it's built," Christmas wrote, along with a heart emoji and a tag to Memphis' Instagram handle.
"(I promise it wasn't a kiss) #2020 #unexpected #christmasabbott #memphisgarrett #bb22 #theangrytherapist."
Not only did Memphis comment on the post with six heart emojis, but he also shared a similar post of his own.
"Sometime people come into your life and you know they just belong. We tried to fight it but fate had its own plan. Excited for the future," Memphis captioned a selfie of the pair smiling.
Christmas and Memphis both competed on Big Brother: All-Stars, the show's 22nd season, which wrapped in late October. They were allies in the house as members of The Committee alliance and became best friends while playing the game.
Given both Christmas and Memphis were in relationships with other people while in theBig Brother house, nothing romantic ever came of their tight bond. However, the pair's flirtatious tendencies had many fans speculating Christmas and Memphis had feelings for each other all along.
Christmas toldUs Weekly that she and Memphis "just started dating" after their respective romances with other people quickly fizzled out once they returned home after the show.
Christmas shared with E! News in a separate interview, "It's hard to pinpoint exactly when I felt my feelings for Memphis grow from just a friendship to more because I believe that our friendship IS what's more."
Christmas said all of their fellow Big Brother houseguests are "all very excited" they finally got together.
"I really didn't think that it would happen for me," Christmas told E! News.
"I wasn't looking for a relationship, I was there to WIN. It's so wild to have this experience because we reverse engineered how society promotes falling in love. Memphis and I got to know one another through real conversations, building trust with each other and not starting with a physical connection. That's a rare thing!"
And Memphis echoed Christmas' sentiment, adding, "Never in my mind would I ever think I would find love thanks to the Big Brother house, but sometimes fate has other plans."
Dating speculation began to swirl when Christmas and Memphis were photographed hanging out at a Florida bar together in November and the image circulated on social media.
