Madonna's heart just got broken. The 50 year-old singer/actress just found out that her 20 year-old boy-toy had spent a romantic weekend in Brazil with lingerie model Luciana Costa.

Another factor influencing the breakup was her intentions to adopt another Malawian orphan, and her relationship with a guy half her age didn't exactly spell "responsible mom".

A source close to Madonna told the Daily Star: "She was drawn to Jesus. But it was just a bit of fun and she's enjoyed herself. But she is growing bored of the relationship and her family comes first. He would ruin her chances of adopting again. And the pictures of him with Luciana made her realize that he'll be better suited to somebody his own age."
