MADONNA is jetting to Brazil this week with her current squeeze, Jesus Luz, but she denies it’s to meet his mom, Cristiane Regina da Silva. She told Page Six, “I am going there strictly for fund raising and humanitarian purposes.” She’s meeting with the governor of the state of Rio de Janeiro, Sergio Cabral, and spon soring a documentary about kids living in the squalid hillside slums. Meanwhile, despite rumors that Luz would join actor/model Adam Senn in the new Dolce & Gabbana campaign, it turns out the Material Girl herself has landed the job. She shot it along with Senn, owner of Chelsea restaurant Il Bastardo, late last week in Brooklyn. A source said, “The campaign was shot by Steven Klein and has a gorgeous vintage Italian look, like ‘The God father.’ “
