World champion boxer Floyd Mayweather, 35, will trade his lavish 22,000 square foot mansion for an empty 6-by-10 ft jail cell today.

The egotistical boxer will report to the Clark County Detention Center in Las Vegas this morning, where he will spend the next 87 days for punching out his baby mama in front of their children.

“Money” Mayweather, who is used to traveling with suitcases filled with cash, will be allowed a maximum of $30 on his books to purchase basic necessities, such as toiletries and underwear. If he’s not in solitary confinement (for his own protection), he will spend one hour exercising or watching TV. The other 23 hours will be spent alone in his cell.

Earlier this year a judge allowed Mayweather to delay the start of his 87-day sentence to train for his fight with Miguel Cotto on May 5th. Mayweather won the fight by unanimous decision, and pocketed a cool $50 million.
