Following some heated performances, fans of the show have speculated if the dance partnership between the TV presenter, 33, and the pro, 26, has developed into more than friendship.
The couple has been storming the leaderboard in the beloved BBC series and the judges have continuously praised the pair for their chemistry on the dancefloor.
‘I find it exciting that everyone’s interested in us enough to take note of all of these things,’ AJ enthused.
‘The way I see it is, everyone can see how well we’re getting on and how hard we’re working in order to try our best each and every week to put in a solid performance.’
When asked whether the rumours about them being more than friends are true or not, she joked: ‘Well, one thing that is definitely for sure is, we are doing a lot of dancing.’
During Halloween week the pair were visited in rehearsals by AJ’s younger nieces and nephews, where she told them: ‘I’m really loving it (Strictly), I love learning new dances, I like all the costumes and I really like Kai’, to which her young nephew Odhran replied: ‘Why don’t you just kiss him?’
AJ also revealed that her nephew expressed concern when Kai danced with Nadiya Bychkova in the professional routine, adding: ‘He got jealous on my behalf… He was like, “who is this?”’
Co-host Claudia Winkleman also told the couple, after they received positive comments from the judges for their Viennese waltz to Dangerous Woman by Ariana Grande, that if there was a time for the pair to snog on air it would be then.
When asked how they react to all the speculation about their relationship, AJ continued: ‘It’s all just a bit of fun, isn’t it?
‘I mean, at the end of the day, me and Kai are just focused on the Strictly experience as a whole, and we’re just focused on dancing and putting our best performance forward each and every week.
‘So none of that stuff bogs us down at all. We don’t have time to be pressed to be totally honest with you.
‘And Claudia is so lovely, and is so kind to us each and every week, so it’s all fun and games.’
This is Kai’s first year on the show, having previously performed on the Irish version of Dancing With The Stars.
Discussing his experience of the competition so far, he said: ‘It’s just been brilliant, every single week has been amazing.
‘Since week one when we came out with the jive and we broke that record, or whatever it was, and the iconic performances we’ve had since then…
‘I’m having the best time, we’re having a ball together, we get on like a house on fire, we train to ungodly hours.’
On Saturday night, Kai and AJ finished top of the leaderboard with their Charleston.
The duo impressed the judges with their routine to Don’t Bring Lulu by Dorothy Provine, Pinky and The Girls, scoring 39 out of a possible 40.
Strictly Come Dancing continues tonight at 7.15pm on BBC One.
