Christina Aguilera, 43, looks very slim in a T-shirt and kinky boots as she ... trends now

Christina Aguilera showcased her newly slender figure in behind-the-scenes images shared to Instagram on Monday.

The 43-year-old singer was in a white T-shirt and black kinky boots. She appeared very thin in the skimpy look after she said she lost 50lbs last year.

The blonde Genie In A Bottle crooner was preparing for her Las Vegas show held at the Voltaire inside the Venetian Hotel.

'Soundcheck,' wrote the diva in her Instagram caption as Heidi Klum, Erika Jayne and Michelle Pfeiffer hit the like button. 'Hmmm, sounds kinda low,' she added in her video.

'What I love about the intimacy at Voltaire at The Venetian Resort is how up-close-and-personal I can be with the audience, a truly modern twist on the performance experience,' Christina has said online. 

In January, Aguilera marked her return to Las Vegas after 2019’s 10-month The Xperience with Burlesqueier.

It is an intimate show at the Venetian’s Voltaire Belle de Nuit, a newly opened venue.

The looker made sure the show was steamy as she also wore a sexy black outfit that hugged her curves while she flirted with her male backup dancers.  

Aguilera added new shows for her residency. Voltaire Bell de Nuit at The Venetian announced 10 new dates have been set for Aguilera's series, running from April to August. 

Those include two shows that were rescheduled from January, which Aguilera canceled due to illness.

This comes after she appeared skinny at the 2024 Grammy Awards in downtown Los Angeles.

The hitmaker graced the red carpet before taking to the stage to present the award for Best Musica Ubana Album alongside singer Maluma.

She stunned in a skintight baby blue gown, highlighting her newly trim physique.
