Floyd Mayweather's 19 y.o daughter Iyanna arrested for stabbing NBA Youngboy's baby mama

Floyd Mayweather's daughter, Iyanna Mayweather, has been arrested for felony aggravated assault with a deadly weapon, and it appears to have been a confrontation over NBA Youngboy.

Iyanna is currently in Houston's Harris County jail after getting arrested at 1:30 AM Saturday. Law enforcement sources tell TMZ, the alleged victim and NBA Youngboy were at his home when Iyanna arrived and told the woman, Lapattra Lashai Jacobs, she was Youngboy's fiancee and Jacobs should leave the house. Jacobs then told Iyanna to leave.
The argument moved into the kitchen, where Iyanna was holding 2 knives.
According to sources, Jacobs stepped toward Iyanna and Iyanna charged at her with one of the knives. Jacobs told cops she didn't feel the first knife wound but then she said Iyanna charged at her with the second knife, stabbing her again.
When EMTs arrived, Jacobs was laying on the floor. She was taken to the hospital. Her condition is unknown. Youngboy, who was home at the time, was briefly handcuffed by cops -- presumably as a precautionary measure -- before being released.
Iyanna told cops Jacobs had incited her by initially pulling her hair outside the house and then running into the kitchen, where the confrontation went down.
Iyanna told cops she had never met Jacobs before.
According to cops, Iyanna stabbed Jacobs multiple times in the bicep ... she was transported to the hospital in stable condition.
Iyanna is a 19 year old singer and social media celebrity.
