Taking to Instagram on Sunday, the Australian professional dancer re-shared a photograph posted to Joe's IG Story which read: "I've said we can get one if they get to the final."
In the photo, Dianne was seen holding a giant silver Christmas tree crafted from reflective baubles, miniature discoballs and glittering tinsel.
It comes as Dianne and her dance partner Chris McCausland, who is Strictly's first blind contestant, have sailed through the competition without having faced a dreaded dance off.

With just three weeks left of the competition, the duo have already been dubbed the "winners" by fans on social media, with several declaring that Chris is the "favourite to win".
If Dianne does get to the final, it will mark only the second time she has made it to that stage of the competition, the first being with her now-boyfriend Joe in 2018.
While Dianne and Joe didn't go on to win, they ended their Strictly journey having gained more than just a friendship. Following the end of the series, Joe wrote on Instagram: "I may not have won the glitter ball, but I’ve won something a million times more special."
Dianne and Joe's ongoing love story
Since relocating from their beautiful country house in Sussex, Dianne and Joe have settled for a sprawling £3.5 million Brighton property as they embrace their next chapter of life together.
"We're so happy," Dianne confessed about her new home to HELLO! in April this year. "We're just trying to make it more cosy and more homely every day."
She added: "We really love it where we are. I think it's [their Brighton home] gonna be home for us for a very long time. You can never say never, but I'm really happy where we are at the moment."
On the subject of whether the couple would ever move back to her native Australia she added: "We probably wouldn't move back at this stage, though I have to say it does get harder being away from family."
While the couple have never spoken about whether or not marriage is on the cards, their fans never fail to leave comments on their sweet couple photos whenever they post together.
"We need a wedding guys! favourite couple ever," penned one fan on a recent post, as another agreed: "Do I see a potential proposal Mr Sugg? Think it’s about time... lovely couple… made for each other."
