Girls Aloud appeared 'stronger than ever' as they performed their final London show on Thursday, despite having to resort to flogging cheap tickets.

The group were forced to slash prices by up to 60 percent after failing to sell out their three-night stint at the O2 Arena. 

Yet despite the last-minute cuts Nadine Coyle, 40, Kimberley Walsh, 42, Nicola Roberts, 38, and Cheryl, 40, looked in their element as they took to the stage in front of the arena - which appeared packed. 

The tour, their seventh overall, and their first without the late Sarah Harding, kickstarted in Dublin in May and will now move onto Liverpool. 

The group looked so confident on stage that a body language expert declared they are now 'stronger than ever'. 

A body language expert declared Girls Aloud 'stronger than ever', despite slashing ticket prices by up to 60%, as they performed their final London show on Thursday 

Speaking on behalf of Betfair Roulette, body language expert Darren Stanton, said: 'With Girls Aloud coming back together this year and looking at their performances after having a long break from performing, it’s clear they have found their feet with their levels of confidence. 

'They’ve grown a lot since they first started but we’ve seen a lot more humour and confidence come through. They’re feeling stronger than ever when we look at their in-sync movements and expressions of enjoyment on stage. 

'Their interactions with each other are a lot more authentic and open, meaning they’re all in better places with each other connection-wise. This is shown through more eye contact and championing each other on stage. 

'For example, we saw Nadine and Cheryl taking the lead by being tactile with each other, as well as initiating hugs and cheering each other on.'

Darren revealed that Nicola was the 'most reserved' member, saying: 'Her body language gestures are more closed and less open than what we see from Cheryl, Nadine and Kimberley. 

'Her eye contact and facial expressions aren’t as strong and consistent. 

'However, she is able to perform and she comes across as very extroverted on stage, which tells us she’s able to channel her nerves and turn those feelings into excitement.' 

While the girls were in their element, some fans were left than impressed after shelling out more than £100 for tickets only to see the prices slashed to £30.  

The 20,000-capacity O2 arena had seating availability in almost all areas, according to ticket sellers AXS. 

Sales were particularly slow for Wednesday, with some areas appearing to be only around 60 per cent sold. 

The band's reunion tour has been marred by drama with provider Ticketek struggling to deliver tickets ahead of their show at the Resorts World Arena in Birmingham and Nadine Coyle awkwardly forgetting the lyrics at their gig in Dublin. 

Girls Aloud was formed in 2002 on ITV's Popstars: The Rivals show with Pete Waterman, Geri Halliwell and Louis Walsh choosing the final line-up.

They sold over 4 million albums in the UK and achieved four number ones with two albums at no 1 as well. They were also nominated for five BRIT awards. The band split in 2013.

On June 19, Cheryl told the crowd in Birmingham that Shakira's Waka Waka – played during the warm-up – was a special tribute to Sarah Harding. 

She said: 'That was Sarah's favourite song when she was going through all of her stuff. It'd get her up dancing and singing, she'd be on Face Time. 

'It made us so happy to see her happy in those darker times so we wanted the spirit of Sarah to start right at the very beginning, and the next best bit is when we hear you guys roar, there's nothing better than that sound.'

Sarah Harding died in September 2021 aged 39 after being diagnosed with advanced stage breast cancer in 2020. 

The group has since raised over £1 million for cancer charities including the Sarah Harding Breast Cancer Appeal.

Kimberly Wyatt said: 'One of the main aims on this tour is to do Sarah justice and give us and our fans that moment to celebrate her. I think they need it, I think we all need it.'

In May, Cheryl almost 'burst out crying' as the group took to the stage in late bandmate Sarah Harding's hometown of Manchester on Thursday.

Sarah's mother Marie sat in the audience as the group paid an heartfelt tribute to her daughter, 

The group struggled to choke back tears as they held hands to sing a beautiful rendition of their 2007 hit I'll Stand by You, which also included Sarah's recorded vocals. 

They do this every night of the tour, with footage of Sarah displayed on the huge screens behind the women. 

Cheryl told the crowd: 'Coming to Manchester has always been an absolute pleasure, It's a really significant evening for us tonight in many ways. Obviously, we all remember Miss Harding's hometown is Manchester'.

'She would have been so proud of the reception we've had in here tonight, thank you so much Manchester for making it special for her, and for us'. 

Cheryl continued: 'Sarah's mam's in here tonight and I'm sure she's feeling all the love and energy in the room. We love you, Marie. When I come down on that podium, the energy I was hit with I could have just burst out of crying there and then.'

Before adding: 'Thank you for making it bearable, and making it a joyous occasion for us all.'

Also every night, the group also put up images of Sarah and play her iconic line from The Promise: 'So, here I am...walking Primrose.' 

The Girls Aloud Show has two shows left: Friday and Saturday at the M&S Bank Arena, Liverpool.
