Mariah Carey is proving she has a good sense of humor!

The music icon, 54, took part in the ‘Of Course’ video trend currently sweeping social media on Sunday. She posted a hilarious clip of her parodying home habits that would fit her diva persona on Instagram and TikTok.

In the video, which she captioned “Sunday Camp! 💅 #ofcourse,” the star first sat back on a leg press machine in what appeared to be her home gym while wearing a sparkling gold gown and platform heels.

“I’m Mariah Carey … of course this is my workout ensemble,” she quipped to the camera, adding, “1, 1000…” as she pretended to countdown the reps in her workout.

The star poked fun at her diva persona in a new social media clip.

Carey then appeared in a white slip dress with feathered sleeves and a signature butterfly ring while lying in bed as a full glam squad get to work on her hair and makeup.

“I’m Mariah Carey … of course my glam squad is on standby,” she said on the voiceover.

The next clip showed Carey sporting a bright pink robe and a pair of sunglasses as she held up her 2020 memoir The Meaning of Mariah Carey.

Mariah Carey is jumping on board the “of course” trend.

Pulling her shades down, she said, “I’m Mariah Carey…of course I’m reading my own book!”

Lastly, Carey could be seen on a sun lounger next to two of her Jack Russell Terrier puppies.

“I’m Mariah Carey … of course my puppies get pampered after they poop,” she said. She then stroked her pooches as she said to them, “Hey babies, yes…”

The self-deprecating clip was appropriately set to Carey’s own tune “Obsessed.”

Earlier this month, Carey — whose split from longtime partner Bryan Tanaka was confirmed in December — entered the new year with “new beginnings” as she posted a selfie from her “bad side.”

In the Instagram snap, the “Queen of Christmas” smiled as she showed the left side of her face while wearing a sparkly silver Retrofête mini dress.

On her 2016 year reality show, Mariah’s World, Carey revealed the origin of her aversion to showing the left side of her face.

She explained to makeup artist Kristofer Buckle that when she was doing her first photo shoot at age 19, a woman on the set told her, “This is your good side, only let people photograph you from your good side, ever.”

From then on, Carey said she “didn’t like” pictures from her left side.
