She can save the world in just four minutes, but now Madonna may have to save her fortune from a rocky relationship.
 
The mega-pop star, 49, is reportedly seeking legal advice on possibly divorcing from her husband of seven years, film director Guy Ritchie, 39.

According to The Times of London, the “4 Minutes” singer has consulted Fiona Shackleton - the same divorce lawyer who made sure Sir Paul McCartney retained his money after divorcing Heather Mills. And with Madge worth an estimated $590 million, there’s plenty at stake.
 
Known for her tough courtroom tactics, Shackleton has been called the “steel magnolia” and also served for Prince Charles during his divorce. Ritchie has also retained a lawyer, according to the paper.
 
Though a spokesman for Madonna has repeatedly denied the two are headed for splitsville, gossip mongers have speculated for years that the Material Girl and Ritchie are on the rocks. The couple reportedly did not have a prenup, which means their assets could be split in half.
