Christina Aguilera has no problem saying goodbye to her 30s.

The ageless songstress turned 40 on Friday and shared a fun, sassy video in preparation of hitting the major milestone.

On Thursday, the star took to social media to share a brief clip proving that even after all these years, she's still got it.

The video begins at Aguilera's feet featuring black and gold heels. The camera then pans up the singer's leg and body, revealing her matching black and gold bodysuit as Megan Thee Stallion's "Body" plays. She also sported a long ponytail in her signature platinum blonde color.
