Xtina embraced the big 4-0 with a gold-embellished black bodysuit that she wore while strutting at home in a new video with Megan Thee Stallion’s “Body” hit bumping in the background. “Comin for you 40!” she exclaimed.

Missy Elliott commented “Happy Birfffffday” before a fan commanded her to put their cover of Rose Royce’s 1976 hit “Car Wash” on Spotify, which the two had recorded for the 2004 DreamWorks animated film Shark Tales.

The “Reflection” singer revealed how arriving at a new decade of her life made her feel in a letter she addressed to her new age.

“Dear 40, What a beautiful concept… to not only be ‘turning’ 40, but to be ARRIVING at 40!” she began her lengthy message. “This ever-present social stigma exists around getting older, but I have ALWAYS embraced it! … I’ve heard it said that some of your best life is lived in your 40’s. You stop giving a f— about all the bullsh–… clarity comes over you, and a new intention sets in with every move you make. I truly believe the best is yet to come and I am READY for it.”
