Scroll down for updates…

Prize fighter Floyd “Money” Mayweather won’t need any of his flashy jewels or fancy cars where he’s going. Today is the day the troubled boxer must turn himself in to authorities to begin serving a 90-day sentence for roughing up his children’s mother in front of them in September 2010.

Mayweather will turn 35 in prison on Feb. 24.

It’s cold on the cell block this time of the year — even in Las Vegas. And Mayweather won’t have his curvy model fiancee, Shantel Jackson, to keep him warm for the next 3 months.

The boxing champ was sentenced to serve 6 months on Dec. 21, but a Las Vegas judge suspended 3 months of his sentence and allowed him to remain out over the holidays. The judge also credited Floyd 3 days for time served.

Mayweather has until today (Jan. 6) to turn himself in at the prison — where Bubba awaits.

Update: According to TMZ.com, a judge ruled today that Floyd Mayweather Jr. won’t have to turn himself in to a Las Vegas jail until June 1, 2012 … so he can fight in Las Vegas on May 5th.

TMZ adds: “His attorney’s justification … Floyd’s a pro who brings in hundreds of millions in profits for the city of Las Vegas — and hey, thing’s get rescheduled all the time … no bigs.”
