The duo – who reached the 2023 BBC One final – were all smiles as they finally got their hands on the Glitterball Trophy.
Dianne, 34, and EastEnders actor Bobby, 20 – who has confessed his “love” for his professional partner multiple times – could be seen beaming in delight.
The Aussie pro wore a black and red dress colour matching with the model’s red shirt and black trousers.
He clutched onto the shimmering trophy – with winners voted by the live tour audience each night – with Dianne snuggled into his chest.
The pair have stayed close following the Strictly Come Dancing live shows, which saw Ellie Leach crowned winner.
As the BBC series aired, rumours of a romance swirled as he branded the red-head “my Juliet.”
Previously, Bobby opened up on his sweet nickname for Dianne.
He told Closer magazine: “I’ve had a few people message and tell me that they’re enjoying mine and Dianne’s partnership and dances, which is lovely, but I only pay attention to a few of the people sliding into my DMs.
“My eyes are focused on my Juliet, Dianne.”
Some fans also suggested he attempted to kiss her in one of their routines.
Meanwhile, Bobby told how he “loved” Dianne for the second time as they tucked into a falafel lunch between live show rehearsals.
Off-stage, the dancer is in a relationship with YouTube star Joe Sugg, whom she met on the show.
The pair share a massive countryside mansion complete with a gym.
Meanwhile, The Sun was first to reveal Bobby’s secret girlfriend – with the pair having already dating for months.
