Floyd Mayweather Jr. Surrenders for 90 day Jail Stint(VIDEO)

Floyd turned himself in to a Vegas jail moments ago. 50 Cent was present in court for support.

Floyd was supposed to surrender back in January, but the judge postponed his jail date so he could fight Miguel Cotto on May 5th. It was worth it ... Floyd won ... and the fight raked in $94 MILLION in pay-per-view sales.

Rich Guy Tips Jermaine Dupri $4k Just For A Shoutout In Vegas

The rapper was spinning at TRYST nightclub at the Wynn Hotel on Saturday … when some super rich guy — known as “Su Su” — dropped $90k on a 15 liter bottle of Ace of Spade Rose Champagne … plus an extra $40k on other fancy booze.

Sources tell us club honchos were so thrilled about the purchase, they asked Dupri to give Su Su a special VIP shout out.

Dupri not only obliged … but he was so impressed with the purchase, he LET THE GUY REQUEST A SONG!! Which — if you’ve ever been to Vegas — never happens.

It gets better … “Su Su” was so thankful Dupri actually played his tune — Pitbull’s “Give Me Everything” — he stuffed an additional $3,800 cash in his pocket as a tip!

“Su Su” tells TMZ … he was “happy” to throw down the cash because he loves Jermaine and thinks he’s a “bomb” DJ.
