Has Money Mayweather’s monstrous temper reared its ugly head outside of the ring? Boxing great Floyd Mayweather Jr. is a suspect in a battery domestic violence case, TMZ said Thursday. Multiple police cars showed up at Mayweather’s home early this morning after receiving a call at 5:03 AM from Floyd’s ex (and baby mama) Josie Harris, who claims the boxer attacked her in a jealous rage during an altercation at her Las Vegas home.

Harris was treated at nearby Southern Hills Hospital and released.

Law enforcement sources say police were unable to find Floyd and are now looking to interview him. This jus that latest spat in a disastrous relationship between Harris and Mayweather. Josie accused Floyd of punching and kicking her inside a Bentley in Vegas seven years ago. Charges were filed but dismissed in 2005 after Harris testified she lied to cops because she was angry that Floyd had left her for another woman.
