She toted her essentials around in a cream leather handbag, she had clearly indulged in some luxury retail therapy at Liberty department store too.

Donning a black T-shirt featuring a motif of Prince’s Purple Rain, Kai continued his look with a pair of charcoal trousers and grey trainers.

They had been joined at the studios by Graziano Di Prima and his fiancée Giada Lini, who certainly didn’t shy away from putting on an amorous display.

The Sicily native enjoyed a romantic kiss with his partner, who put on a leggy display in a chic blue minidress.

The rehearsals come after Nadiya recently moved her things into Kai’s place after growing close over the last few weeks, according to The Sun.

They are thought to have been dating since January following Nadiya’s split from her ex-fiancé Matija Škarabot.

A source said: ‘Moving in together was the obvious next step for Nadiya and Kai. They’ve grown so close and it just made sense.

‘Kai helped Nadiya move in her belongings this week and they’re excited about making their property feel like a shared home.’

MailOnline contacted representatives for Nadiya and Kai for comment at the time.

Nadiya took to Instagram on Monday and shared a snap of her and Kai holding hands across the table at the swanky London venue The Ivy.

The pair put on a loved-up display in the photo as Kai affectionatly held Nadiya’s hand after their Strictly Come Dancing tour rehearsals.

Nadiya and Kai first went public with their relationship after they were spotted walking hand-in-hand through Belfast airport earlier this month.

The professional dancers had just touched down after jetting in from Luton airport to watch co-star Giovanni Pernice ‘s live show.

Both wearing sunglasses, they strolled through the arrivals lounge looking very ‘loved up’ according to onlookers, who told how the pair made no attempt to hide their feelings for each other.

One told MailOnline: ‘They looked like any normal couple breezing through arrivals holding hands.

‘They were wearing sunglasses but didn’t seem to mind that people clearly recognised them from Strictly. Nadiya was giggling and the two of them looked totally loved up.’

The pair’s show of affection came two weeks after they were spotted kissing at a dance event in Leeds, which raised funds for a charity set up by rugby league legend Rob Burrow, who was diagnosed with motor neurone disease in 2019, and has close links to Nadiya’s 2021 series celebrity partner, Dan Walker.

Their relationship was first revealed in January after MailOnline reported that Nadiya had split from her fiancé Matija Škarabot.

Kai comforted Nadiya during her break-up and the pair’s friendship developed into a romance on the Strictly Live Tour, where they were later spotted kissing in a Newcastle hotel bar.

Nadiya returned to her home in Slovenia last month to be with her seven-year-old daughter Mila and mother Larisa — who both continue to live with Matija, who is Mila’s dad.

The footballer threw a welcome home party for Nadiya but clearly she now only has eyes for her Strictly co-star, who was partnered with AJ Odudu in the recent series.

It was recently confirmed the pros would both be returning to the 2022 series of Strictly Come Dancing and are now waiting to see if they will be paired up with a celebrity partner.
