Madonna now a billionaire

Madonna has a new net worth of $1-billion.

The Girl Gone Wild singer - who has four children, Lourdes (16), Rocco (12), David (7) and Mercy also seven, - recently became a billionaire, according to the New York Post.

The 54-year-old star - who was named the top earner in pop music in 2012 - was previously estimated to have a personal fortune of around $700-million, but has now earned more than a billion dollars from her successful career in showbiz after investing in several additional money-making ventures recently.

Her MDNA world tour, which saw her perform 72 sell out shows last year, grossed over $305-million, and also saw her rake in $75-million in merchandise sales and $10 million in TV rights and DVD sales.

Madonna has also enjoyed success off stage as her perfume saw her earn $60-million.

She is also a investor in the popular drinks brand Vita Coco and gym chain Hard Candy, and retail experts estimate she takes home $10-million from her clothing line Material Girl, which she runs with her teenage daughter.
