The Sugababes joined fellow singers Macy Gray and Kimberley Walsh at Usher’s star-studded final show at London’s O2 Arena on Wednesday night, bringing his mammoth Past Present Future tour to its close.

The King of R&B, – whose full name is Usher Terry Raymond IV – finally completed his staggering tour, after wowing crowds with his hits like Yeah, Burn, U Remind Me and OMG since August.

The singer is set to bring the globetrotting tour to Down Under next, with four shows each in Melbourne and Sydney.

And Keisha Buchanan, Mutya Buena and Siobhán Donaghy were among the VIPs putting on edgy displays at the concert, before celebrating with Usher at his European tour wrap party at The Yeah Man. 

Keisha, 40, appeared to have not aged a day since shooting to fame in the girl group over two decades ago, in an effortlessly stylish all-black ensemble.

She put on a leggy display in a tiny miniskirt teamed with a leather jacket and matching knee-high heeled boots.

Her long raven hair was styled sleek and straight, while she accentuated her ageless beauty with a light palette of radiant makeup.

Keisha posed alongside bandmate Mutya, 39, who cut a typically glamorous figure in a daringly short fluffy miniskirt and bejewelled boots.

Leaving little to the imagination, she paired her skirt with a sheer sparkly shirt with a plunging neckline, putting her ample cleavage on full display.

Meanwhile, Siobhán, 40, opted for a more understated outfit, looking on trend in a pair of black leather trousers with silver studded details.

She added a fashionable green bomber jacket over the top and trainers, while pulling her fiery red locks up into a chic updo.

R&B songstress Macy, 57, looked to be having a ball at the gig and afterparty, keeping comfy in a grey hoodie and brown oversized trousers.

While Girls Aloud star Kimberley, 43, opted for effortless sophistication in a chocolate brown blazer over a matching lowcut top.

The mother-of-three added simple blue jeans and trainers underneath, while giving her look some added glamour with gold earrings and a radiant face of makeup.

The Sugababes’ appearance at the show comes after they embarked on a ‘new chapter’ and released their first single in two years.

In March, the trio revealed their new track Jungle marking their return, after parting ways with their record label BMG to go independent.

Sharing their elation at the new song, they said in a statement: ‘We are so excited to release ‘Jungle’ and cement this new chapter for us, after what has been an incredible 3 years on the road. 

‘As soon as it was written, it felt like the perfect thing for people to hear first. A song about escaping the 9-5 grind, we hope everyone can let their inner animal out when they hear this!’

The single – produced by Jon Shave (the man behind Charli XCX’s Grammy winning BRAT album) –  mixes the girls’ unmistakable harmonies with a blend of 2 step, garage and alt-pop.

Meanwhile, the group have been writing new material with none other that Little Mix star Jade Thirlwall, now simply known as JADE. 

The Round Round hitmakers revealed that they’ve so far recorded a verse and a chorus on the track for the singer, but the project has yet to be completed.  

Speaking to NME about about presenting JADE with her BRIT Award for Best Pop Act recently, Keisha shared: ‘It was lovely, and we actually had a writing session with her a couple of weeks ago, which was cool.

On writing with JADE, Siobhán added: ‘The whole thing was very relaxed: a no pressure situation. You [Keisha] were putting on your makeup to go out and JADE was putting on her makeup to go out, and we were all just writing. It felt exciting.’

Meanwhile, the girls have set their sights on taking to the coveted Pyramid stage at Glastonbury, noting how it is ‘definitely on out wish list’.

However, Keisha notes that she’d like the girls to have some new hits under their belts first so that they don’t appear to just be another nostalgic act.  

She added that she wants their set to feel ‘fresh and new’ and for them to be ‘relevant’, adding that the girls hate the word ‘reunion’ as it’s not ‘where they’re at’. 

Meanwhile, the band have been on the road for their biggest ever UK and European tour since last month, kicking off on April 8 in Leeds, before they are set to wrap up in Milan this month.

Keisha, Mutya and Siobhan formed the iconic girl band in 1998, but the lineup then went through several shake-ups after Siobhan left in 2001.

She was replaced by Heidi Range – with Mutya and Keisha eventually being replaced in the mid-2000s by Amelle Berrabah and Jade Ewen, respectively.

The trio won back the rights to their name in 2019 and have since gone on to huge success with a plethora of sold out shows in both in the UK and internationally.
