Madonna is reportedly having a fling with a Brazilian male model. The "4 Minutes" singer met Jesus Luz in Rio de Janeiro while on a shoot for American magazine W, and the pair became so close she invited him to join her on the Sao Paolo leg of her "Sticky and Sweet" world tour.

A source told the New York Post newspaper: "She was very interested in him. He's there with her now and photographer Steven Klein is helping him get along with everyone." Madonna and Jesus reportedly struggled to keep their hands off each other when they met, and did little to hide their fledgling relationship from onlookers.

Another source said: "Everyone knows they are ficando - which is a Portuguese expression that means they are kissing and doing other things but without any obligation of being faithful or getting into a relationship afterwards."

Meanwhile, Madonna is said to be "thrilled" at reports her estranged husband Guy Ritchie is dating Jemima Khan. Guy and Jemima - who was previously married to Pakistan cricket legend Imran Khan and dated Hugh Grant - attended a dinner party together earlier this month.

The pair also went to a star-studded Christmas bash over the weekend, where other guests included Stella and Mary McCartney, Lily Allen, Sir Mick Jagger and Kevin Spacey. A friend of Madonna said: "It's not like she's asking him for details, but she's thrilled at the prospect of him moving on. It makes things easier for everybody."
