However, in subsequent interviews with the pair, viewers have noticed a certain frisson between the pair - and in a chat with Phillip Schofield and Rochelle Humes today on This Morning, they did little to quash the rumours.

Official news on whether these two are dating is yet to be confirmed, but 2014 Strictly winner Caroline Flack was spotted kissing professional dancer AJ Pritchard at the 2019 NTAs.
Phil, who asked the question everyone wanted to know the answer to, grilled the pair by asking about the dating rumours, with Joe immediately saying, "Here we go! Do you know what, it’s so nice, I’ve met such a good friend in Dianne..."
Phillip then leaned forward, asking, "And...?" causing the pair to burst into flirty laughter. Joe replied, "We haven’t got time to think of anything like that! We’re so busy dancing."
But that wasn't good enough for Phillip, who said, "Is that a no?", to which Joe smiled and replied, "We’re so busy dancing! We haven’t got time!"
SURE, JOE. SURE.
Although neither of the pair confirmed they're dating, they didn't officially deny it either - something a lot of This Morning viewers picked up on, and took to Twitter to share their thoughts.
One wrote, 'Joe and Dianne have me CONFUSED', as another added, 'I fully expected Joe and Dianne to deny the rumours they’re dating when Philip asked but he just laughed awkwardly and said “we’re so busy dancing...” like he couldn’t deny it WHAT DOES THAT MEAN.' sic
Strictly Come Dancing continues on Saturday on BBC One at 6.35pm.
