Strictly’s Bobby Brazier looks tired as he and Dianne Buswell leave a grueling 10-hour day of rehearsals for their Argentine Tango

Dianne Buswell and Bobby Brazier left a tiring 10-hour stay at a London dance studio on Thursday, where they rehearsed their Argentine tango.

It was a long day for the 20-year-old EastEnders actor and the 34-year-old professional dancer as they performed the routine ahead of Saturday’s live show.

Bobby and Dianne ditched the gym clothes and looked effortlessly stylish despite the long hours in the studio.

The actor flaunted his model look in a skin-tight gray turtleneck sweater and dark blue pants with brown loafers.

Dianne, on the other hand, sported long legs in a blue mini dress, which she paired with a white trench coat and a camouflage bag.

The two, who will be dancing to “Sail by Awolnation,” made their way to a taxi while Bobby sat in the back seat of a taxi, distracted by his phone.

Dianne appeared to be in good spirits after their week six cha-cha-cha performance where they scored 30 points.

But the Long hours in the studio come when the competition gets hotter.

Layton Williams, 29, and Nikita Kuzmin, 25, who are always at the top of the leaderboard, were also pictured leaving rehearsals on Thursday evening.

However, Nikita appears to have suffered a setback when he emerged from the studio wearing a knee brace and Nadiya Bychkova, 34, stepped in to help Layton rehearse.

The couple will perform a Jive to Shake Ur Body by SHY FX and T.Power feat. Tue in the show on Saturday.

Layton, 29, scored an impressive 36 points during last Saturday’s live show after his co-stars vented their frustration at having to compete against the West End star.

Layton has been on stage since the age of 12, when he played the title role in the West End musical Billy Elliot.

A Strictly insider reported anger and annoyance at Williams being so much more experienced than other contestants, saying he was at least on the same level as his professional partner Nikita, which “goes against the spirit of the show”.

The source said: “Of course there have always been dancers of different standards on Strictly, that’s part of the greatness of the show.”

“But that’s ridiculous, he’s just as good or even better than his professional partner.” The playing field here is so uneven that it’s impossible for any of the other participants to have a chance of winning, even if the spectators enjoy it , to follow a celebrity’s journey.

“Although there is no rule that professional dancers cannot participate, it is absolutely against the spirit of the show.”

“Look at someone like Krishnan Guru-Murthy, he’s built a huge following and is wonderful to watch, and Angela Rippon. But they’re blown out of the water every week by someone who’s a professional dancer.”

A Strictly spokesman declined to comment.

A Strictly insider told MailOnline Layton was “not the first person with dance experience” to have appeared on the show [others include Kimberley Walsh, Maisie Smith and Abbey Clancy].

They added that he was “never trained in Latin and ballroom dancing and was booked because he has a fantastic personality.”

Williams’ appearance on Strictly comes five years after pop star Ashley Roberts was criticized by Strictly fans for being given an unfair advantage because she studied dance in her youth.

The Pussycat Dolls singer kept ending up in the bottom two places because the audience was against her. The backlash, which repeatedly reduced her to tears, was so intense that even presenter Tess Daly appealed to voters to “cut her a little slack”.
