Gemma Atkinson was spotted gazing adoringly at the Spanish dancer, 27, as they waited for a taxi after finishing practice ahead of the tour’s launch next week.
He could be seen putting his arm around her as he leaned in to share a cheeky kiss.
Both stars were dressed casually for the day of training, with Gorka keeping warm in a black jacket and yellow hat while the blonde beauty wore a hoodie and leggings with her golden tresses pulled back in a low ponytail.
Gemma and Gorka have been hitting the training room hard in preparation for the tour alongside their fellow Strictly 2017 stars including: Debbie McGee and Giovannia Pernice; winners Joe McFadden and Katya Jones; Susan Calman and Kevin Clifton; Jonnie Peacock and Oti Mabuse; Davood Ghadami and Nadiya Bychkova; Gorka’s celebrity partner Alexandra Burke and Gemma’s partner Aljaž Škorjanec.
Yesterday, Gemma uploaded a cute picture of several of the cast bundled on top of each other during their lunch break, along with the caption: “Lunch time pile on!”
The sweet snap, which she shared with her 521,000 Instagram followers, showed her lying on the floor next to a beaming Gorka, with Giovanni and Debbie jumping on top of them, while Aljaž and Joe also squeezed in on the action.
Gemma and Gorka have been the subject of much speculation about their relationship since early in last year’s series of Strictly.
They recently sparked yet more claims of a fling when she shared their workout on social media before filming themselves taking a well-earned breather.
Gorka also set tongues wagging when he included a image of them cuddling up together in his best nine Instagram pictures of 2017.
Gemma put her arms tenderly around him as they got very cosy in the group shot, which also showed several of the rest of the cast of Strictly.
