Floyd Mayweather's teenage daughter faces up to 99 years in jail after allegedly stabbing her boyfriend's baby mama twice in a bloody row.

Yaya, 19, reportedly stormed boyfriend YoungBoy Never Broke Again's Houston home and after discovering Lapattra Jacobs inside at 1.30am, the boxing champ's daughter "grabbed two knives and charged at Lapattra".

According to reports: "The incident reportedly occurred at around 1:30 a.m. last Saturday, when Yaya demanded Jacobs to leave the rapper's Houston home. Jacobs refused and demanded Mayweather to leave, which prompted a physical fight between the women."
