The TikTok star is vying for the Mirrorball Trophy on Nov. 21.
Now, it's almost the season finale, and D'Amelio, 18, shared a look back at some exciting and fun personal moments throughout the past two months.
D'Amelio posted a bunch of photos on Instagram, writing in the caption, "some dwts bts!!! i can’t believe the finale is only two days away :( sad that it’s almost over but so excited for you all to see these next two dances!!!"
In the post, there are a few photos of D'Amelio with her mother, Heidi D'Amelio, who also competed in this season of DWTS, as well as a shot with D'Amelio and Ballas.
The rest of the photos show unique behind-the-scenes moments, like when D'Amelio was painted bright yellow to dress up as Marge Simpson or when she smashed a bug in her dancing shoes.
The Instagram post has over 845,000 likes, and D'Amelio's DWTS co-star Trevor Donovan, who was eliminated from the competition last week, commented, "🤘💚," on the post.
Many of D'Amelio's 48.9 million followers also commented on the images, with many people proclaiming their support for the star ahead of the finale.
One said, "Charli going to take home the W."
"Can’t wait we will miss watching y’all sm ❤️😍," another wrote.
The finale of this season of DWTS will air on Nov. 21 at 8 p.m. EST on Disney Plus.
The couples will have to perform their last two dances: a redemption round dance chosen by one of the judges and a freestyle dance.
