Christina Aguilera struts her stuff in head-to-toe hot pink at Dolce & Gabbana Alta Moda event

This Barbie can sing.

Christina Aguilera belted out her hits in style at the Dolce & Gabbana Alta Moda welcome event in Sardinia, Italy over the weekend, rocking an all-pink ensemble to hit the stage — and showing off her recent weight loss in the process.

The “Genie in a Bottle” singer, 43, shared a video of herself leaving the event at the Forte Village resort on Instagram Sunday, captioning the clip, “Buona notte 🇮🇹🤍.”

In the video, she sported the same hot pink satin Dolce & Gabbana corset she wore for her performance, but swapped out her pink feather boa for a piece of sheer pink fabric draped across one shoulder and trailing down her back.

The “Beautiful” singer kept the Barbiecore vibes going with matching long pink satin gloves and thigh-high boots, wearing the same piles of dazzling necklaces she showed off during her performance.

Aguilera wore her blond hair down in a wavy style, showing off a coordinating pink makeup look.

“Thank you @dolcegabbana for having me” she wrote on her story, adding plenty of pink emojis and a “buona notte.”

Her performance in Italy follows the singer sparking Ozempic rumors while showing off a noticeably slimmer physique in May, and fans couldn’t help but weigh in on her figure — and her fabulous outfit — in the comments of her new Instagram post Sunday.

“DIAMONDS ARE A MATERIAL GIRL’S BEST FRIEND, QUEEN! Been waiting for a full pink moment from you this era! A FEAST FOR THE EYES!!! 💕💗💓💞💎💞💓💗💕” one Instagram user wrote.

“Surgery and ozempic got her looking top heavy now 😂” another added, while a third chimed in, “Oh Oh Ozempic!!”

Whatever she’s doing, it’s clearly working.
