There is definitely some beef going on between NBA YoungBoy's baby's mama and his current girlfriend, Yaya Mayweather. By the way, Yaya is Floyd Mayweather's daughter. TMZ reports Yaya, real name Iyanna, was arrested for allegedly stabbing Lapattra Jacobs, YoungBoy's baby's mom. It all went down Saturday morning and the confrontation apparently happened over the rapper. So here is how it went down. YoungBoy and Lapattra were at his home and Yaya popped up claiming to be the rapper's fiancee and Lapattra should leave. Yaya claims Lapattra pulled Yaya'a hair outside and the argument moved to the kitchen and you know there are knives in kitchens and that's when Yaya held two of them and then charged at Lapattra. Lapattra was taken to the hospital.
