Cardi B's sister Hennessy Carolina is getting complimented on her nipple piercings – not hard, given that the 25-year-old had hers on show this week. The younger sister to "WAP" rapper Cardi B showed up on neither her own Instagram nor her sister's one on Tuesday, instead popping up on the new account Cardi has set up for 2-year-old daughter Kulture Kiari. A video shared showed Hennessy being the best auntie ever with Cardi's adorable little girl, but there was an oops moment. Check it out below.

Scroll for the video. It comes as Hennessy makes headlines for thanking God after a drunk auntie joke. It also definitely looked like the model and Fashion Nova face was enjoying Kulture's company.

The video, shot indoors, showed Hennessy inside sister Cardi's luxurious mansion and enjoying some one-on-one time with Kulture. Hennessey was in a living room area and backed by a fancy pillar, also bouncing little Kulture on her lap while wearing a super-flourishy orange dress with giant puff sleeves and what wound up being a very revealing neckline.

Hennessy, rocking her blonde bob hair and attentively playing with Kulture as the toddler wore a onesie, then suffered her wardrobe malfunction as she realized, a little too late, that a lapel from her dress had slipped, making the dress fall open. A quick manoever saw her try and regain her modesty.

A caption, meanwhile, seemingly came from Kulture, reading: "Happy Birthday auntie @hennessycarolina .I love you! Thank you for always buying me gifts that I destroy in 2 days??It’s sooo fun!!!"

See the reactions after the video!

The video has brought in a very mixed response, with one of the most popular comments actually picking up on another aspect of the dress – Kulture's dribbly mess, it would seem, with a comment reading: "Go change your dress, it's getting dirty." The user added cry-face emoji, though.

"I saw herr nip were pierced" was a comment gaining over 270 likes. "I saw it too," another replied. Hennessy herself replied, writing: "Thank you aunties babyyyyyyy anything for you! I love youuuu so muchhh ! ???????."

Hennessy is earning her cash on the 'Gram big-time. Alongside influencing for the Fashion Nova giant sister Cardi has collections with, the beauty is an ambassador for Rihanna's SavagexFenty lingerie line.

"Macaroni in a pot" was the epic "WAP" caption to a recent pineapple undies promo from Hennessy as she promoted 32-year-old RiRi's merch. Hennessy joins other SavagexFenty faces including singer Normani and "Euphoria" actress Sydney Sweeney, plus pop face Christina Milian.

Cardi, meanwhile, has been showing off her "back fat" and "body" in a frontless bra. Scroll for that.
