Nicole Scherzinger bounces back from suffering horrific burns as she leaps around the stage in a sparkly bikini as The Pussycat Dolls' problem-ridden reunion tour hits London

Nicole Scherzinger bounced back from suffering horrific burns as she leaped around the stage at the Pussycat Dolls tour in London's O2 Arena on Tuesday.

The singer, 48, proved that the show must go on as she performed in a sparkly bikini after accidentally spilling boiling water over her leg last month.

She showcased her impressive flexibility while high-kicking on stage alongside her bandmates. 

Nicole, Kimberly Wyatt and Ashley Roberts have suffered multiple setbacks since their comeback began in September.

The tour has already been plagued by poor ticket sales, member feuds, cancelled dates and horror injuries. 

As well as Nicole's horror burn, Kimberly has been recovering from a hip operation and Ashley broke down in tears after 'freaking out' ahead of performing a solo. 

Even before the tour kicked off, the group faced controversy following the exclusion of three of the group's founding members: Carmit Bachar, Jessica Sutta and Melody Thornton. 

The group announced their comeback in March along with their first single in six years, Club Song, produced and co-written by Mike Sabath.

However, they were forced to axe the entire US leg of their comeback tour due to dismal ticket sales.

Ashley, Nicola and Kimberly had originally announced they would be reuniting as a trio for a massive 53-date run across the UK, Europe and North America.

But in a humiliating blow, they were forced to scrap the 33 dates they had planned in their native US as well as Canada after poor sales left arenas 80 per cent empty.

Even after slashing the price of seats to just $30, organisers had no choice but to pull the plug only a month before they were set to have their first show in Palm Desert, California on June 5.

Sharing a statement to Instagram, the band wrote: 'When we announced the PCD FOREVER Tour, we hoped to bring the show to fans across the world.

'After taking an honest look at the North American run, we've made the difficult and heartbreaking decision to cancel all but one of the North America dates.

'Our UK and European dates are still moving forward as planned, and the response has been incredible, with several shows already sold out.'

They said: 'We are putting everything into making this show a true celebration of the music and the memories, for the fans who have been with us from the beginning and those discovering us for the first time.

'We're working hard to create the kind of show we've always dreamed of bringing to you. We cannot wait to bring this reunion to Europe and make these nights unforgettable.'

The trio kicked off their tour in Copenhagen in September followed by shows in Paris, Warsaw and the UK.

Those who bought tickets from Ticketmaster or AXS were informed they would receive a full refund automatically, while those who bought theirs from third-party resellers have been advised to contact their point of purchase.

Elsewhere, fans were left baffled last month as a reported technical issue stopped Nicole performing their hit song Buttons during their show in Poland – leaving Ashley and Kimberly awkwardly dancing on stage.

The gig was thrown into chaos when lead singer Nicole was missing from the first half of the song, with it being said that a technical problem or a wardrobe malfunction was to blame.

After Nicole had just performed a medley of her solo tracks, the concert then moved into a climactic moment for their massive global hit Buttons.

But the lead singer was nowhere to be seen, leaving just Ashley and Kimberly performing the impressive choreography while a backing track played.

In a fan video shared to Instagram, the highly awkward moment saw the women fail to step in and sing Nicole's part, simply chiming in with their minimal vocals with a large gap between them where Nicole should have been.

The blunder attracted plenty of comments from bewildered fans questioning why Ashley or Kimberly didn't seize the moment to show off their vocals, with many noting that former member Melody would have stepped up.

While Nicole did a majority of the vocals, Melody, 42, occasionally sang lead vocals and major ad-libs in some Pussycat Dolls numbers, with the singer famously stealing the spotlight by belting out unassigned harmonies during a performance of Buttons at the 2006 American Music Awards.

Tickled fans penned in the comments: 'Where’s Melody when you need her?'

'THIS WAS YOUR CHANCE LADIES'; 'Melody would’ve said watch this'

'glorified oh oh girls, THAT WAS UR CHANCE KIM & ASHLEY!!! but neither of them stepping up to fill in shows me EXACTLY why those 2 were asked to return. Carmit & Melody would have moved to center & taken that opportunity IMMEDIATELY.'
