NINETIES pop fans have been left doing a double take after spotting a new video of her on stage.
The stunning singer, 43, was captured on film while performing in Las Vegas but not everyone has recognised who she is.
The stunning lady in question is US star Christina Aguilera, who burst onto the pop scene in 1999.
It has now been 25 years since the release of her debut single Genie In A Bottle and she is still as fierce as ever.
In fact, even if her appearance didn’t give the game away, her iconic vocals should have.
Christina – aka Xtina – wowed the crowd as she belted out What A Girl Wants before ending the song with a series of runs and trills.
The Beautiful star, who had her first taste of fame as a child, styled her long platinum hair in bunches and wore a sexy monochrome outfit with coordinating stockings.
But one fan admitted on TikTok: “I genuinely never would have guessed that was her.”
Another said: “You could have given me 50 guesses and I never would have guessed this was Christina Aguilera.”
And a third questioned: “Why does Christina look soooo different?”
Christina’s big success came in the late 90s when she was just 18 and continued through into the noughties.
However, her career in showbiz began long before then.
Just before her 10th birthday, Christina took part in US reality show Star Search and her talent for singing was made clear.
Two years later, she landed a place in The All-New Mickey Mouse Club and starred on the show alongside some now very famous faces.
Xtina’s fellow Mouseketeers included Ryan Gosling, Justin Timberlake and Britney Spears.
Later, Christina and Britney went on to become pop rivals after both launching their solo careers in 1999.
The two ladies continued to dominate the charts throughout the noughties and sold multi-millions of records between them.
Christina now has two children, Max and Summer, and she has been in residency in Las Vegas, US.
The Dirrty singer reportedly lost 40lbs (2.8st) before kicking off her shows in Sin City but she admitted that the world’s ‘obsession’ with her weight was “particularly painful”.
“When you’re a teenager, you have a very different body than when you’re in your 20s,” Christina told Life & Style magazine.
“I started to fill out, and then that was unacceptable because it was like, ‘Oh, she’s getting thicker.’ Then I had industry people, ‘They liked your body and how you were as a skinny teenager’.”
However, as she has aged, Christina is less affected by comments from around the globe.
“I have a maturity now where I just don’t give a f*** about your opinion. I’m not going to take it on,” she said.
“It must be your responsibility to take up your space. Other people’s opinions of me are not my business.”
