Bobby Brazier's 'mystery pal' is a glamorous fashion stylist from Essex, MailOnline can reveal.
The 20-year-old Strictly finalist was pictured snuggling up with Sienna Penman, a day after losing the Glitterball trophy to winner Ellie Leach.
During a restaurant dinner, the pair laughed and hugged, with sources confirming to MailOnline that they have been close friends since school.
Sienna, from Epping, supported Bobby after the Strictly final on Saturday after he performed three routines with dance professional Dianne Buswell, 34.
Since the BBC series ended, Bobby has shared two black and white photos on his Instagram profile of himself dancing with partner Dianne, while the Australian pro said winning the competition wasn't important after discovering true 'happiness' during appearing alongside the EastEnders actor.

A source told MailOnline: 'Bobby and Sienna have been good friends for years, since school.
'They stuck to each other on most things and had a lot to talk about after Bobby's time on Strictly.
'Obviously they get on well, but so far there is nothing romantic between them and Sienna has a boyfriend who she is in a long-term relationship with.'
According to reports, Bobby is dating fashion consultant Boadecia Evans, although the couple has yet to publicly confirm their romance.
Speaking to presenter Claudia Winkleman on one of Strictly's live shows, Bobby revealed he was sharing a bed with someone and had woken him up by performing a dance move.
He said: 'I woke up at one point doing this… I woke myself up doing that, and the week before the person I was sharing a bed with turned around and said this is the industrial twist …'
There was also speculation about Bobby's relationship with dancer Dianne, who is fourteen years his senior, after he referred to her as his 'Juliet'.
However, Dianne's romance with former Strictly partner and YouTube star Joe Sugg, 32, appears to be still going strong after he supported her in the final at the BBC studios.

On Instagram, Joe said: “I couldn't be more proud of you Dianne, you made Bobby the best ballroom and Latin dancer.
'Every Monday morning at 5am I will drop you off at the station with bright eyes and a smile on your face, excited to teach and produce brilliant choreography every week.
“You may not have won the trophy but you captured the nation's heart last night and over the course of the series and really showed everyone what you can achieve.”
Dianne and Joe made it to the Strictly final in 2018, but lost out winning the series to Stacey Dooley and Kevin Clifton, who are now also in a relationship and share a baby together.
