Floyd Mayweather Jr. knows how to win a woman’s heart. When his girlfriend, Chili of TLC, asked him to appear in a reality series VH1 is shooting about the resurrection of the pop group, the undefeated welterweight champ surprised her by showing up at a photo shoot in chinchilla boxer shorts and a cape. Chili, who dated Usher for several years, swooned. TLC performed with Justin Timberlake last week at his charity gala in Las Vegas. Bill Diggins, Chili’s manager and the show’s executive producer, said it will debut in March.
