Strictly lovebirds Nadiya Bychkova and Kai Widdrington prove they’re getting serious by taking big step in relationship

STRICTLY lovers Nadiya Bychkova and Kai Widdrington have shifted their relationship up a gear and moved in together.

The couple, who The Sun revealed started dating in January, are sharing a London home now Nadiya is back in the UK after travelling to Slovenia to see daughter Mila.

They have become inseparable since her break, having also travelled to Northern Ireland last week to watch co-star Giovanni Pernice’s solo show in Belfast.

A source close to the couple 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.”

Southampton-born Kai, 26, comforted Nadiya, 32, following her split from Slovinian footballer Matija Skarabot, 34 — the father of her daughter Mila, five.

Their friendship turned into a relationship soon after, blossoming while appearing on the Strictly Live tour, where they were pictured by The Sun kissing in a bar.

After the tour, Nadiya returned to her house in Slovenia to see Mila and her mother, who live with her ex Matija in their family home.

Nadiya and Kai will be spending more time together on the upcoming Strictly Professionals tour, where they will play 36 dates across the UK, beginning later this month.
