The Genie in a Bottle hitmaker currently performs at The Venetian Resort until March.

In the TikTok video, the pop singer ditched the makeup as she sat on the concert stage.

During the nearly two-minute clip, Christina rehearsed with the band as the drums rolled and the organ played.

The singer sat barefaced as she paired her oversized white T-shirt with knee-high black leather boots.   

Her messy, long hair flowed past her shoulders and over her chest.

“Hmmm, sounds kinda low,” she said at one point.

As the footage continued, Christina belted her voice out as she practiced with the backup dancers. 

She flaunted her slender figure and showed off her long legs while strutting down the runway.

“Soundcheck,” Christina captioned the post.

Fans jumped to the comments section after noticing the star’s glam-free appearance.

“Wow, I did not recognize her at all,” one said.

“Didn’t recognize her until she did her iconic vocal run!” another mentioned.

“[Christina]’s looking like she did in 2010. Burlesque era but with a little dazzle of age. She looks good,” a third added, referring to her 2010 musical.

“What did she have done?” another user wrote.

“Nobody said Christina looked bad. She’s just completely unrecognizable. Beautiful but unrecognizable,” a commentator chimed.

The Lady Marmalade star revealed she lost up to 50 pounds through diet, exercise, and lifestyle changes.

In April 2021, Christina admitted to Health Magazine that she felt pressure surrounding her appearance during the ’90s.

“I think we all have our good days and our bad days in how we feel about ourselves. Entering this business, I hated being super skinny,” the mom-of-two reflected.

“Once I turned 21, I started filling out a little bit, and I loved my new curves. I appreciated having a booty.”

“I have a hard time looking at the early pictures of myself because I remember feeling so insecure.

“I would never want to relive my 20s — you’re so in your own head and finding your confidence,” Christina concluded. 

Christina shares her daughter, Summer, with fiancé Matthew Rutler.

The Voice alum also shares her eldest child, Max, with her ex-husband Jordan Bratman, whom she married in 2005.
