Christina Aguilera Channels Megan Thee Stallion as She Celebrates Turning 40 in a Sexy Catsuit

Christina Aguilera is saying hello to 40 in style.

The singer celebrated her newest age milestone on Thursday night by posting a video of herself rocking a skintight black-and-gold catsuit and heels to her Instagram page.

Strutting her stuff down a hallway to the tune of "Body" by Megan Thee Stallion, Aguilera let her long blonde locks fall in a straight cascade down her back.

At the end of the clip, the "Dirrty" hitmaker — who officially celebrates her birthday on Friday — flipped her hair over one shoulder and looked back, giving a sexy stare to the camera.

"Comin for you 40!" she captioned the fun footage, which Megan, 25, re-shared to her Instagram Story alongside a string of heart-eye emojis.

This isn't the first time Aguilera has expressed her appreciation for Megan's music. In August, she gave a nod to the "Savage" star and her fellow rapper Cardi B in the form of a shout-out about their hit summer single, "WAP."

In the snapshot on her Instagram, Aguilera stunned in a white rib-knit body-con dress, bright-red lipstick, a silver pendent necklace and clear-rim sunglasses as she took a dip in her pool.

Aguilera seemingly felt empowered to post the red-hot Instagram photo after listening to the NSFW rap song, which celebrates female sexuality.

"#WAP got me feelin some type of way 💦," she captioned the photo.

Last year, Aguilera turned 39 at a blowout bash that doubled as a glam Christmas celebration. "When your birthday falls on the best season of the year ... " she captioned three photos of herself in a festive red sequined scoop-neck dress, posing in front of pink Christmas trees.

The footage from her party showed Aguilera entering the party venue, which was decorated with red, pink and gold balloons, as well as even more pink Christmas trees.

While she made her grand entrance, her red dress accidentally came open, revealing one of her black pasties — but the singer wasn't fazed by the wardrobe malfunction, and cheekily flashed the pastie again.

"Entering the last year of my 30s with the best vibes … dancing, singing, salsa-ing," Aguilera captioned the video post. "What a night. SO thankful for everyone in my life who's been on this journey with me. Who has stuck by me through and through. 'She came, she conquered. Get ready 2020.' "
