Strictly's Shirley Ballas, 66, pokes fun at those wild dance moves in a hilarious clip with her stunt double after baffling fans by doing backflips and the worm in results show

Strictly's Shirley Ballas has poked fun at those wild dance moves in a hilarious new Instagram clip with her stunt double on Monday. 

The BBC star, 66, baffled fans during the pre-recorded professional's dance on the results show as she busted out impressive backflips and the worm.

Now Shirley has shared a behind-the-scenes video with stunt double Alexis Warr, who rocked a matching black and white polka dot dress and curly brunette wig to the judge.

Recreating the viral Family Guy trend, the pair joked: 'One of us is going to have to change.'

Shirley added: 'POV: You bump into yourself backstage.' Before writing in the caption: 'It totally was me doing the flips… @bbcstrictly @alexis_warr.'

The Queen of Latin was thrown into the air by Vito Coppola before being replaced by Alexis who performed multiple backflips and finished with the worm while pretending to be Shirley. 

Fans praised Shirley and Alexis for the 'smooth transition' with a few admitting they were 'fooled' by the swap. 

They wrote: 'Well on first watch, you had me fooled. Alexis is a very good younger Shirley ❤️ ❤️ I loved that group dance. The best in years imo!!'

'It was such a smooth transition that my children did not believe me when I said it wasn’t you doing the flips - they were adamant it was you' 

 'Oh Shirley I’ve been preaching to my partner how wonderful you are as a fellow dancer.'

'It wasn’t our Shirley after all!'

'That, was genius! Loved it.' 

Fans were originally left baffled by the wild moves and questioned whether it was really Shirley performing the acrobatic moves or if it was a stunt double. 

They wrote: 'Wait a damn minute… Shirley Ballas busting out these moves was not on my bingo card'; 'who was Shirley's stunt double?'

'Did they just use a stunt double for Shirley Ballas complicated dance moves and backflips??;

'DID SHIRLEY BALLAS JUST BACKFLIP INTO A WORM OMG I LOVE THIS SHOW #Strictly #StrictlyComeDancing; 

'So who was doing the flips for Shirley?;

'Omg! Was this Shirley Ballas or a stunt double!!? She's 66, people! Incredible;

'A special mention to Shirley Ballas's stunt double...no..no one noticed..!!;

'Imagine if that really was Shirley breakdancing'.

It comes as Delta Goodrem is left 'heartbroken' as she is forced to pull out of this weekend's Strictly Come Dancing following a serious rib injury. 

The singer, 41, will not be joining the remaining 12 couples on Saturday as they take to the dancefloor for Icons Week, instead her and professional partner Kai Widdrington will be given a bye into next week. 

Delta, who was meant to portray Olivia Newton-John as her Icon, explained that she is 'absolutely gutted' after topping the leaderboard with her Salsa but has been 'advised by doctors to rest'.

Sharing a statement on It Takes Two on Monday, host Ellie Taylor read: 'I'm absolutely gutted that a rib injury means I won't be able to dance on Strictly this week.

'I've been loving every second of this experience, so having to sit this one out is heartbreaking - especially after the high of Saturday night. 

'I cannot tell you how much I love being a part of this magical show. I'm going to focus on resting and recovering, and hopefully I'll be back on that dancefloor very soon.'

She concluded: 'Thank you so much to everyone for all the love and support. It's so appreciated. I'll be cheering everyone on from the sidelines this week! Sending all my love, Delta xx'

A Strictly spokesman added that doctors have advised the star to rest so she will be able to compete the week after. 

They said: 'Due to injury, Delta Goodrem has been advised by doctors to rest and, as a result, will not dance on this weekend's Strictly Come Dancing. 

'In line with the rules of the show, Delta and Kai will receive a bye through to next week when it is hoped they will be able to dance again. 

'We wish Delta the very best as she continues her recovery.'

After topping the leaderboard on week two, all eyes were on Delta and Kai as they took to the floor with their Salsa to Always There/Ain’t Nobody by Jocelyn Brown/Chaka Khan.

Loving what she saw, Motsi gushed: 'Brought the D.I.S.C.O, absolutely loved it, your highlight!' with an excited Craig noting: 'a-may-zing!'

And the judges were as generous with their scores as they were with their feedback, awarding the Australian singer and her partner 33 points – the highest score of the series so far. 

Meanwhile on Sunday's results show, Melanie Walters and Aljaz Skorjanec became the second couple to leave Strictly. 

The Gavin and Stacey star found herself fighting for survival in the dance-off after receiving a score of 17 on Saturday. 

Joining her at risk were former footballer Shaun Wright-Phillips and his partner Alexis Warr, who had finished last on the leaderboard with 15 points.

But after both performing again it was Melanie who found herself hanging up her dancing shoes having failed to impress the judges with her Charleston to Ooh Ahh... Just A Little Bit by Gina G.

Receiving one vote from Motsi Mabuse, the other three judges Shirley, Craig Revel Horwood and Anton chose to save Shaun and Alexis.

Leaving the competition, Melanie looked to be fighting back tears as she said: 'Well to tell you the truth, I thought I was going to be out last week so I have had an extra week with this wonderful soul.'

Aljaz told the star: 'It is difficult to put into words, but if I was going to say something profound and beautiful it wasn't going to be looking like this. 

He added: 'Look you are an ultimate professional at what you do and that's why you are so successful in what you do and you showed me what hard work really is. 

'We started every day with "partner let's have the best day ever" so let's finish this with a hug and thank you for every single bit in rehearsals and every single step on that floor. Thank you.' 

They then took to the floor for the last time for a final twirl as Melanie wished her fellow contestants all the best for the rest of the competition.  

The couple will join Ellie Taylor on Strictly It Takes Two on Monday at 6.30pm.
