The Pussycat Dolls reunited on The X Factor: Celebrity live final this evening.
X Factor judge Nicole Scherzinger joined her former bandmates for their first gig together in 10 years.
It comes after it was confirmed that the group - Nicole, Kimberley Wyatt, Ashley Roberts, Carmit Bachar and Jessica Sutta - will head out on a new tour to celebrate their 20th anniversary.
However Melody Thornton will not be a part of the reunion, which will see performances from April 2020 with tickets on sale now.

Ahead of the performance, a source told The Sun that the band were planning to go "all out" with their performance.
"The X Factor producers approached Nicole about the idea of performing with the girls and she jumped at the chance," an insider shared. “It’s going to be their first big performance of the reunion and will be extra special for Nicole because of her role in the show.
“Having the Pussycat Dolls perform is a real coup for Simon Cowell and he has told Nicole to pull out all the stops to make sure their routine gets people talking."
The X Factor: Celebrity final aired this Saturday night on ITV from 7:10PM.
Last week's episode saw a performance from Louis Tomlinson while another two contestants were eliminated.
Footballer turned actor Vinnie Jones and rugby trio Try Star were given the boot in the semi-final elimination of the series.
Now just four acts are left in the running to be crowned the winner of The X Factor: Celebrity and winning a record deal.
The X Factor: Celebrity series concludes on November 30 at 7:10PM.
