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.
