GOING COMMANDO: Kelly Rowland, who attended Jean Paul Gaultier’s show Thursday, said she was grateful for a sunny Paris day after braving downpours to perform an outdoor concert in Singapore the previous night. “It’s beautiful outside,” she gushed. The singer has a new single in the charts, “Commando,” and is preparing to release an album in September. Jimmy Jean-Louis, meanwhile, looked cool as a cucumber sipping mint tea in a pristine white suit. “If it gets dirty, it gets dirty. That’s what things are for,” he mused. The actor recently finished filming psychological thriller “Sinking Sands” in Ghana, and is producing and directing a documentary about the earthquake in his native Haiti. Meanwhile, Spanish heartthrob Roger Berruezo just finished shooting “Mil cretins” with Catalan director Ventura Pons, but his main gig is the soap opera “Gavilanes,” in which he plays heartthrob Oscar. Apologizing for his poor English, he described his character thus: “I am a boy who works in a hotel. I stay with different girls every day.” We get the picture.
