Slash and his wife Perla Hudson are breaking up after 13 years of marriage

Slash and his wife, Perla Hudson, who are breaking up after 13 years of marriage, did not sign a prenuptial agreement when they got married 2001.

Sources close to Perla say that she has already hired people to figure out how much money Slash made during the time they were married. She believes the legendary guitar player has made tens of millions of dollars since 2001 and she's entitled to 50%.

Slash filed for divorce late last month, citing "irreconcilable differences" and wants joint custody of their two kids: 12-year-old London and 10-year-old Cash.

It' not the first time things have been rough between Slash and Perla. Back in 2010, Slash tried to get a diverce, but then decided to give the marriage another try. After that they renewed their wedding vows.
