pros Nadiya Bychkova and have shared a glimpse into their low-key relationship with a rare photo.
The professional dancers are believed to have during the latest series of the BBC One competition.
Since then, the pair have kept their relationship under wraps aside from a few sightings together.
However, Kai, 26, shared a selfie of them together looking loved-up as they enjoyed a night at the Queen and Adam Lambert concert at ’s O2 Arena on Sunday.
In the snap, the couple are seen hugging with the packed-out crowd behind them as Nadiya, 32, affectionately places a hand on Kai’s chest. He simply captioned the image with a red heart emoji.
They weren’t alone for their date night as fellow Strictly pro Giovanni Pernice appeared to be third-wheeling the couple. The dancer, who is believed to be single after splitting from Love Island star Maura Higgins last year, looked as though he was having the time of his life as he threw his arms up while his best pal Kai took photos of him.
Reports of a romance between Kai and Nadiya first emerged in January when they were seen looking close and arriving at hotels together following the end of the latest Strictly series.
It wasn’t until April when after months of speculation about the nature of their relationship.
‘We’ve been seeing each other properly for a couple of months now,’ she told the Daily Mail Magazine.
Nadiya went on to describe how much they’re enjoying each other’s company despite having ‘very little free time’.
‘It’s early days and we’ve been rehearsing for the Strictly Professionals tour, so there’s been very little free time.
‘But we’re getting to know more and more about each other day by day. He’s kind and compassionate and makes me laugh. I feel very relaxed with him.’
Their relationship came after Nadiya, who is a mother-of-one, split from her ex-fiancé Matija Škarabot.
