Talk about a bombshell!

Christina Aguilera took to Instagram this week to show off her latest fashion moment, and the 38-year-old "Dirrty" hitmaker has never looked better as she prepares to celebrate another birthday.

In a post containing two photos of the same look, Aguilera dons a structured orange dress with long sleeves, exaggerated shoulders and a seriously plunging neckline that puts her curves on display.

"Sagittarius energy," she captioned the pictures. "A big birthday mood loading.."

Aguilera is set to turn 39 on December 18, one week after she shared the photos.

Fans were quick to praise the singer for how "gorgeous" she looked, flooding the comments section with flame, heart . and heart-eyes emojis.

"HOW CAN YOU BE SO PERFECT MY QUEEN?" someone wrote, while someone else declared, "You are so beautiful."

Aguilera has been busy touring Mexico over the last couple of weeks, and she's gearing up to launch her first-ever Las Vegas residency, The Xperience, which kicks off at the Zappos Theater on December 27, with the current run of dates scheduled to end on March 7.
