Strictly Come Dancing reveals first look at glitzy launch show as hosts Emma Willis, Josh Widdicombe and Johannes Radebe make their long-awaited debut and the celebs finally meet their pro partners

Strictly Come Dancing's long-awaited return is just hours away, and fans have been given their first taster from the glitzy launch show.

The BBC hit is entering a new era with the arrival of new hosts Emma Willis, Josh Widdicombe and Johannes Radebe, five new professional dancers and a pivot to sign stars that will help bring the show into the social media age.

Snaps from the launch show Emma, Johannes and Josh arriving in the Strictly ballroom for the first time, while the professional dancers take to the floor for a sultry group number.

No doubt in disbelief that their huge presenting gig has arrived, one image also shows the new hosting trio sharing a group hug. 

This year's celebrity lineup will feature Love Island winner Dani Dyer, EastEnders' Lacey Turner, Gavin and Stacey star Melanie Walters, Australian singer Delta Goodrem, Big Brother host Will Best and Kim Kardashian's hair stylist Chris Appleton.

Also joining the celeb cast this year are actress Jaime Winstone, former footballer Shaun Wright-Phillips, Olympians Dame Sarah Storey and Tabby Stoecker, Love Island winner Cach Mercer, House of the Dragon star Bethany Antonia, Graeme 'The Dogfather' Hall, Emmerdale's Lawrence Robb and social media sensation John Nellis. 

The launch will see the celebrities finally discover their professional partners, and they will take to the floor in the first live show on September 26. 

Josh was the first to confess on Thursday he is feeling the nerves ahead of the first show airing on Saturday night.

He told The One Show hosts Alex Jones and Roman Kemp: 'It's nerve-wracking, we've been waiting for so long to do this. I've been living in a ball of fear. But since the launch I just want people to see it. Can we just show it now?'

The One Show presenters then tried to tease out of Johannes what his role will be on the show, which has so far remained somewhat of a mystery.

However, he kept the mystery to himself and coyly said: 'What's lovely, is that you won't get to know on the launch. But I say tune in to find out. You have to, it's fun!'.

They also discussed the dance that will take place in the first episode and consist of all of the couples switching partners. 

Emma explained: 'There's much more movement, they've never done it before. There's 3 groups of 5 and they'll have their own dance. They are paired and it's like speed dancing. They're all learned a routine. The music will start, they will dance, and then they switch. And they do five or so seconds and then 30, and they switch.'

Josh added: 'I think we should do it every week, it's so entertaining!'

Johannes said after seeing how much work went into the routine he admitted he was glad to no longer be one of the professional dancers.

He said: 'I'm so glad I've changed roles, it's a lot of work and it's never been done before.', before backtracking moments later.

Emma said she is constantly looking at Johannes when people are dancing to 'check if he looks jealous', as he admitted: 'The fomo (fear of missing out) is real!'

The presenters will also dance in an ensemble routine, as Emma revealed she had been practicing at home with her husband Matt Willis. 

She said: 'I like to be thorough, so JoJo had been teaching us, I was going around the supermarket with a trolley, I made Matt learn it with me. I sent it to JoJo to ask if it was right!'

On Saturday, viewers will finally get to see this year's pairings unveiled, as the celebrities discover which professional dancers they've been partnered with.

Already it has been reported that Neil Jones has once again missed out on a celebrity partner, and has been benched for the seventh time after being injured in rehearsals earlier this month.

Last month, Strictly became embroiled in a fresh 'fix' row as it's claimed nine of the celebrities have past dance experience.

Throughout the years, the BBC dancing show has come under fire for signing up stars who have some form of dancing or performance history, and it appears that this year is no different if new reports are to go by.

The Sun reported that with nine out of the 15 celebrities having past experience, 60 per cent of the cast will have an advantage over their fellow competitors.

Strictly has gone through a massive shakeup for its 24th series. The show's long-time hosts Claudia Winkleman and Tess Daly made the shock announcement they were quitting during last year's series, heralding the start of the overhaul.

After months of rumours as to who would replace them, it was finally announced in May that seasoned presenter Emma, comedian Josh and the show's professional dancer Johannes had landed the coveted gig.

The show shakeup has also included a focus on social media stars, disappointing loyal fans of the BBC's flagship show, who have criticised the 'weak' line-up, claiming there aren't enough 'household names'.

Insiders have revealed the broadcaster has a casting strategy as part of its overhaul and has been deliberate in its targeting of celebrities with big social media followings in a ploy to attract younger viewers to the show.

It has been suggested this is to follow a similar, hugely successful social media strategy employed by its US counterpart Dancing With The Stars. 

Celebrities such as Kim Kardashian's hair stylist Chris Appleton might not be a household name, but he does boast a huge social media following with 4million fans on Instagram.

Sports YouTuber John Nellis has an even bigger fanbase, with 15.7million YouTube subscribers.

Dancing With The Stars has used their celebrity contestants' followings to their advantage, introducing a TikTok Night last year – an episode which saw the contestants perform viral dance routines, sparking an uptick in interaction from younger viewers.

The Dancing With The Stars TikTok account now has more than 5million followers, in comparison to Strictly's 670,000.

And even before this year's Strictly line-up was announced, the professional dancers fell victim to the same strategy. In recent months popular dancers Nadiya Bychkova, Karen Hauer, Michelle Tsiakkas, Luba Mushtuk and Gorka Marquez have all been given the boot.

It's understood pros with bigger online followings have been chosen over dancers who are not so TikTok friendly as the series tries desperately to attract a younger audience.

One example appears to be axed Bychkova, who has 214,000 Insta followers, while Dianne Buswell, with 1.2million Instagram followers and 973,000 on TikTok, has kept her place in the line-up.

Meanwhile five new young pros have been recruited with ballroom champ Maddie Ingoldsby boasting 364,000 TikTok followers. 

The trio of new hosts also have a strong online presence. Comedian Josh Widdicombe has more than half a million Instagram followers on his personal account whilst the Insta page for his hugely popular podcast Parenting Hell has 250,000.

Emma Willis has 2million Instagram followers and fan-favourite dancer Johannes Radebe, who will act as a co-presenter this year, has 458,000 followers.   

The insider has explained that the BBC struggles to attract big-name celebrities these days, because the landscape has changed.

The source told The Sun: 'Crucially the pipeline that used to feed these big shows has changed.

'Boyband and girlband stars aren't as prevalent any more and, once upon a time, getting someone from a soap or a big drama was a massive deal, but now even that has diminished somewhat.

'Now, though, social media is continuing to boom and big stars from the world of TikTok, YouTube and Instagram are known to a vast section of society.'

Strictly Come Dancing kicks off on Saturday, September 19th at 7:25pm on BBC One.
