Christina Aguilera might be 43 but she’s on fire.

The celeb was looking like the best version of herself recently during a live performance gig and her sultry appeal left many speechless.

The singer showcased a very slender figure through images she posted on her Instagram during the evening hours of Monday.

She certainly dropped a huge amount of weight in the past couple of months and it wouldn’t be wrong to state that fans were loving her new revamped appeal.

We’re so thrilled to see this change, adding one loyal friend while another asked the celeb to share her secrets because this was beyond incredible.

Christina put on a very tiny outfit that showed how much work she’s putting into her workouts these days as the attire featured a sweetheart neckline which she chose to wear across her over-the-knee boots.

The singer explained how she was on her way to Las Vegas for a performance and that explained her very bold and daring outfit. “I’m going to the stage in Sin City”- she added and just like that, people couldn’t help but praise her.

Another person mentioned how she really enjoyed playing the song Dirty and those who were there to attend also got a special rendition of the hit tune.
