MADONNA - MADONNA AND LEON REMAIN FRIENDS

Pop star MADONNA and former boyfriend CARLOS LEON didn't last long as a romantic couple, but still remain great friends as they raise their ten-year-old daughter LOURDES together. The HUNG UP singer was in New York City last week (ends15JAN07) promoting her new film ARTHUR AND THE INVISIBLES and caught up with her former flame. The pair had dinner Thursday night (11JAN07) at Nobu 57 and were careful to arrive and leave the restaurant separately. A witness tells PageSix.com, the two held hands and seemed "very flirty, very friendly, they were having a wonderful time." Madonna's spokeswoman LIZ ROSENBERG adds, "They set a good example for other couples who have kids. It's lovely they get along and remain friends."
