Ellie Leach and Bobby Brazier have sparked romance speculation.
The 22-year-old actress - who won last year's 'Strictly Come Dancing' alongside her pro partner Vito Coppola - and the 'EastEnders star, who also took part in the Latin and ballroom show last year, are said to have grown close on the current 'Strictly Live Tour'.
An insider told The Sun newspaper: "Bobby and Ellie are the talk of the tour.
"Their friendship has grown and grown, and they’ve been spending nearly all their free time together before and after performances.
"They’ve been having their meals together, and flirting increasingly openly."
The pair are said to be planning to "go public with their romance" soon.
The insider added: "The chat on tour is they may have enjoyed a cheeky snog, and will go public with their romance any week now.
"They’re both hugely popular characters, and make a really cute couple.
"There are also endless commercial opportunities for them as a pair because they are both hugely in demand, with the world at their young feet.
"Everyone is very excited about this hot new pairing."
Ellie had previously been romantically linked to 31-year-old Vito during the latest 'Strictly' series, but the pair are just good friends.
In November, Vito told how he had bonded with Ellie's family over his love of her mum's gravy.
Speaking in a joint interview with Ellie on 'Lorraine', he said: "Ellie's family have become like another family for me. Honestly, I've been so, so lucky.
"And your mum does the best gravy ever. I ate the entire pot.
"Of course, we'll stay friends and people who stay in your life forever."
Also in November, Ellie admitted she hoped to remain "good friends" with Vito when the show came to an end.
She told OK! magazine: "We really, really get along and we have a lovely friendship.
"I hope we can continue that.
"We’ve got a really good relationship where we kind of know what the other needs. Vito even lets me have power naps during training."
