Kimberly Wyatt says Christina Aguilera has earned the right to be a diva - because she is so talented

Speaking to the UK edition of Closer magazine, she said: "I spent a lot of time with her.

"She's an interesting human, but I have such an appreciation for her talent.

"She's one of the best voices of our generation - standing next to her and hearing her sing, the strength in her voice is the real deal.

"She might be a bit of a diva, but you know what? She can have it."

The Hits Radio DJ has "so many brilliant memories" of the 18 years - on and off - she spent in the Pussycat Dolls, such as when she "did a kick line with Jack Black" and saw Snoop Dogg "dressed as Santa Claus - called Santa Bizzle".

Kimberly - who was in the Pussycat Dolls with Nicole Scherzinger, Ashley Roberts, Jessica Sutta, Melody Thornton and Carmit Bachar - revealed: "I have so many brilliant memories, like performing at The O2 and seeing over 10,000 people sing 'Stickwithu' with their phones up in the air - I still have that little snapshot in my head, it's just unforgettable.

"Way back in 2002, I did a kick line with Jack Black while dressed as a popcorn kernel for the MTV Movie Awards!

"The amount of experiences I had just because I've been in and amongst all these people.

"Snoop Dogg dressed as Santa Claus - called Santa Bizzle - I mean, that's a memory!"

Kimberly - who has three children with her husband Max Rogers, Willow, 11, Maple, nine, and Ford, six - reunited with her 'Jai Ho! (You Are My Destiny)' bandmates in 2019, and was set to go out on the road with them again for a Greatest Hits world tour the following year, but it got cancelled due to the COVID-19 pandemic.

Nicole confirmed it had been cancelled via an Instagram post, citing "evolving circumstances", and Kimberly - who was on ITV1's 'Dancing on Ice' at the time of the announcement - was "in tears" after she found out from Google and fan messages because of "the amount of sacrifices we'd all made to make it happen".

She told the Mirror: "I'll never forget, being on that main stage ice, getting ready for one of our first live shows and getting the news from Google and fans saying 'It's been cancelled!' - I was in tears, I couldn't believe it, the amount of sacrifices we'd all made to make it happen to have it ripped from our hands was devastating, I still feel devastated."
