It’s been well-documented that Floyd Mayweather Jr. spent two months in Clark County Detention Center (in Nevada) in 2012 for a domestic abuse conviction.

During a conference call this week, Mayweather spoke in humble tones. He thanked  everyone in his camp for putting together a terrific promotion for his May 4 welterweight title defense against Robert “The Ghost” Guerrero at MGM Grand in Las Vegas (on Showtime pay-per-view). He also thanked his publicist for doing what he said most would not.

“I like the way Kelly Swanson, she wrote me letters every day,” Mayweather said. “Thank you. You’re the best publicist in the world.”

Swanson was conducting the conference call.

“I’m not just saying that,” Mayweather said. “I don’t know about anybody else’s publicist that wrote them every day when they were locked up.”

Swanson, who is based on Washington D.C., is one of the top publicists in the game. She said via text message Friday that she did try to write Mayweather every day because Mayweather has done a lot for her.

“It was the least I could do while he was going through it,” she texted.
