Cardi B's testimony went viral as she changed wigs and outfits each day of the trial - the length of her fingernails becoming a focus multiple times in the case.
During closing arguments, Cardi B wore a black and white polka dot suit with a red bow, her black hair tied up.
Since this is not a criminal case - but a civil one - the jury had been asked to decide if Cardi B should be held liable for injuring Ms Ellis and, how much, if anything she should pay the security guard for pain and suffering.
Cardi B testified that she's being sued for $24 million and that Ms Ellis was looking for a payout. Ms Ellis' attorney in closing arguments said that it was up to the jury to decide a dollar amount to compensate Ms Ellis.
Ultimately, the jury cleared the rapper entirely in the case.
Outside the courthouse in Los Angeles County, a handful of fans showed up to support the rapper.
Christine Orozco who lives near the court showed up with a hand drawn sign that read, "If the nail don't fit, u must acquit," a pun referencing another Los Angeles celebrity trial - that of OJ Simpson, where the gloves, not the fingernails, were a subject of debate. She said Cardi B read the sign and laughed.
"She had a round tip that day, not a sharp tip," Ms Orozco said of Cardi B's fingernails. "She read the sign. She was squinting to see it. She laughed."
