Christina Aguilera showcased her newly slender frame in new images by Dennis Leupold shared to Instagram on Tuesday evening.

The star has dropped a substantial amount of weight in the past few months and seems thrilled to be showing off the change.

The singer looked incredible in the tiny outfit that had a sweetheart neckline as she added white over-the-knee boots.

The 43-year-old singer wore the look for her show in Las Vegas.

There was also a photo with her partner Matthew Rutler as well a sweet image of her small purse dog. The star was then seen with Megan Fox and boyfriend Machine Gun Kelly as well as Jason Derulo.

‘About this weekend,’ was all she wrote in her caption as she noted she was in Las Vegas. 

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.  

Also this week, 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.

Tickets for the new shows will go on sale Friday, February 16, via voltairelv.com.

Fans who had tickets to the original January dates will receive information on how to purchase tickets in advance of the public on-sale date.

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

The Genie in a Bottle 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.

The long-sleeved number boasted a high neckline and a hem that gracefully swept the floor, transitioning into a small trailing train.

The appearance at the 66th annual celebration comes as Aguilera’s own Grammy journey boasts 21 nominations and five wins. 

Her inaugural victory dates back almost 25 years to 2000 when she clinched the coveted title of Best New Artist. 

Christina was joined by a cavalcade of celebrities ready to enjoy live performances by Billie Eilish, Dua Lipa, Luke Combs, Olivia Rodrigo, SZA and Travis Scott

Hosted by Trevor Noah, this year’s celebration will air live at 8 p.m. ET/5 p.m. PT on CBS and its streaming service Paramount+.

This year SZA tops the nominations with a total of nine nods, including Album of the Year, Record of the Year, and Song Of The Year. Taylor Swift follows close behind with six nominations, and will also be competing against SZA in the three aforementioned categories.

The majority of Swift’s nominations were for her acclaimed album Midnights and its single Anti-Hero, which earned some of the best reviews of her career.

That track is up for Record of the Year, a category that honors the artists who recorded the song and its producers and engineers, as well as for the Song of the Year category, which honors songwriters. SZA’s track Kill Bill has also been nominated in both categories.

Swift has already made history in the Album of the Year category, currently tied for three previous wins with music legends Frank Sinatra, Paul Simon and Stevie Wonder.

However, she is now poised to become the first-ever person to win the category four times if Midnights ends up victorious this year.

She recently flaunted her incredible figure after losing 40lbs over the years.

The  songstress showed off her weight loss as she put on a dazzling display during her Las Vegas residency opening show last month.

She previously said she ‘hated being super skinny’ and has started embracing and ‘loving my new curves’, according to Health.

After years of fluctuating back and forth, she is now maintaining a slender and strong physique while ‘having a booty’.

Her secret has been dedicating herself to a healthy, balanced diet and a rigorous exercise regime.

When she welcomed her son Max, now 15, in 2008, she was subjected to scrutiny over her weight gain. 

Two years later, she started losing weight for her role in her 2010 film Burlesque.

However, that same year, her weight fluctuated again while going through a divorce from music composer Jordan Bratman, 46.

The Beautiful hitmaker also shares nine-year-old daughter Summer with her longtime fiancé, Matthew Rutler, 38. 

Following her son’s birth, she reportedly dropped 40lbs by restricting her daily food intake to 1600 calories and following the Rainbow Diet.

As part of her diet, she sticks to a plant-rich regime and consumes brightly colored fruits and vegetables every single day.

She has since given up on dieting and focuses on eating clean now, she revealed to L’Officiel Italia in 2020.

She noted that instead of being restrictive, she tries to consume more of whole foods and less of sugary snacks.

Besides her balanced diet, she also likes to stay very active and do a wide-ranging workout routine to keep fit.

She reportedly enjoys yoga, boxing, strength training as well as cardio exercises and will workout two to five times a week, according to In Touch Weekly.

She has also trained with celebrity fitness coach, Tee Sorge, to incorporate weight lifting and cardio to maximize calorie burn and maintain her curves.

In 2008, her trainer revealed to Glamour that she worked out ‘up until she was eight months pregnant and then started back up a few months after [her son] Max was born’.
