The Pussycat Dolls' first performance back together has sparked controversy after X Factor viewers dubbed it "inappropriate" for the family show.
The girl band took to the stage for the first time in a decade after announcing their reunion world tour, but not everyone was pleased with their return to prime time.
"That was an absolutely disgraceful spectacle," one Twitter user wrote of the routine, which ended with the scantily-clad singers being soaked in water.
"Before the watershed, with kids watching! Their excessively revealing and totally inappropriate 'outfits' and S&M style dance moves wouldn't have been out of place on an adult channel!"
The Pussycat Dolls performed a medley of their greatest hits, including 'Don't Cha', 'Buttons', before debuting a new song called 'React'.
The group donned various combinations of mesh and leather for their outfits, with lead singer Nicole Scherzinger wearing a revealing bodysuit.
"Highly inappropriate content for this time of the evening. Pussycat dolls look like they belong in a strip club, not for prime time family viewing," another tweet read.
"Not good roll models [sic] for young girls."
"Please remember kids watch this, being so sexually provocative and flaunting sex on prime time tv isn’t so great," said a third.
Scherzinger, who went on to become an X Factor celebrity judge following the Pussycat Dolls' split, appeared unfazed by the complaints online.
"Wasn't expecting that... were you," she captioned a clip of the performance on her Instagram page.
The Pussycat Dolls' reunion tour kicks off in the UK in April, before they arrive in New Zealand in May to headline the So Pop concert series.
