Floyd Mayweather 'barely recognizable' after losing weight and growing out his hair in jail

Maybe Floyd Mayweather Jr's lawyer was right when he complained about the quality of food in jail.

In a new photo the undefeated prizefighter tweeted, Mayweather is 'barely recognizable,' having lost a great deal of weight and muscle tone and grown out his hair behind bars.

Mayweather was released from jail in Las Vegas earlier this month after serving 60 days of his 90-day sentence. He allegedly battered his ex-girlfriend in front of two of their three children in September 2010, but struck a deal that avoided felony charges.

The Las Vegas Review-Journal cited an anonymous friend who said, 'I didn't recognize him. He looks thinner, especially in the face.'

Mayweather's lawyer tried unsuccessfully to spring his client from jail just days after he went in, saying the quality of food and water, along with the cramped conditions, threatened to permanently damage the boxer's physique.

Last year, he earned $85million by promoting -- and winning -- just two of his own fights.

The 35-year-old welterweight boxer weighed 151 pounds when he stepped into the ring in May.

On Friday, he made an appearance at his gym driving a Lamborghini Aventador -- a $375,000 super car.

A lot has happened in Mayweather's world since he was jailed June 1.

With no television in his solo cell, he could not see arch rival Manny Pacquiao lose his WBO welterweight title on June 9 to Timothy Bradley.

Mayweather, who goes by the nickname 'Money', was also not around to celebrate last month when Forbes magazine named him the world's highest-paid athlete for 2011.

And he missed fiancee Shantel Jackson's private birthday bash last week at a Las Vegas steakhouse with friends.

Review-Journal celebrity columnist Norm Clark noted that Mayweather sent diamonds. But Mayweather is now a free man, even if his next opponent is not immediately clear.
