The Pussycat Dolls delighted fans when they reunited for the first time in a decade on Saturday's X Factor: Celebrity final, but their performance didn't impress everyone and led to hundreds of complaints.
The girl group took to the stage for their first public performance in ten years to perform a medley of their best known hits, including Buttons, When I Grow Up and Don't Cha, along with a rendition of their new song React.
X Factor judge Nicole Scherzinger and band members Carmit Bachar, Kimberly Wyatt, Ashley Roberts and Jessica Sutta put on an energetic show along with a troupe of male back-up dancers.
Following the show, Scherzinger tweeted that it was "good to be back with my girls".
However, the five-piece's performance sparked 419 complaints to UK watchdog Ofcom.
An Ofcom spokesperson commented: "We are assessing the complaints against our broadcasting rules, but are yet to decide whether or not to investigate."
The final of The X Factor: Celebrity saw former The Only Way Is Essex star Megan McKenna crowned the first winner of Simon Cowell's spin-off show.
The Pussycat Dolls are set take to the stage for a special performance in Dublin's 3Arena on April 5, 2020.
