Madonna has split from her boytoy lover Jesus Luz, according to a new report.

The Material Girl is said to be single again after the Brazilian underwear model called off their relationship, citing their age difference and busy schedules, according to the Chicago Sun-Times.

The newspaper alleges, "It not only was totally amicable, but it was Luz who initiated the split. Apparently, the 23-year-old Brazilian realized their age difference (she's 51) and overall lack of mutual interests nixed a long-term relationship."

Madonna began dating Luz after they met at a December 2008 photoshoot for W magazine - just weeks before her divorce from director Guy Ritchie was finalised.
