The rumoured couple, who reportedly fell out during rehearsals, were seen hugging as the camera panned away from Mollie King and AJ Pritchard while they said their goodbyes on Sunday’s results episode.
Although Marquez is partnered with Alexandra Burke and Atkinson with Aljaz Skorjanec, they have reportedly grown close over the course of the series.
Despite playing down romance rumours, the pair reportedly had a bust-up a few days before and finally buried the hatchet on Sunday.
“Gemma wasn’t impressed to see Gorka flirting with a beautiful dancer,” a source told The Sun.
“Everyone could see that Gemma was looking at him and had a face like thunder. He stormed back to his room and Gemma followed in the same direction very shortly afterwards.”
Atkinson recently insisted that she is just good friends with Marquez, despite rumours of a budding romance.
“People love drama and people love romance,” she told Lorraine Kelly. “So they try and pinpoint what they can get.”
Atkinson and Marquez will take part in this Saturday’s live final, alongside Burke, Joe McFadden and Debbie McGee.
