THANKS to Madonna's high-powered pals, she isn't recovering from her injuries alone. Madge, who recently got tossed from her horse in the Hamptons, has reunited with her Brazilian man-candy, Jesus Luz, and insiders are crediting her friends in the fashion world for it. Marc Jacobs "wrote a letter of support for Jesus' work permit" to allow him to stay in the country, said our source. "Marc campaigned for Jesus, saying he is highly talented and a necessity to the label." Last week, Women's Wear Daily reported Dolce & Gabbana's fall-winter menswear campaign will feature Luz. Our tipster said, "All these fashion lines are hiring Jesus as a favor to Madonna. As long as he can legally work in the US, they can be together." Madonna's rep said she's "not at all involved in managing the career of Jesus Luz. His Dolce job was arranged through his agents," and Madonna hadn't asked anyone to help him. Jacobs' rep had no comment. PAGE SIX, NY Post
