The GUNS N' ROSES guitarist filed for divorce from Perla, his wife of 13 years, in December, 2014 - citing irreconcilable differences and requesting joint physical and legal custody of their two sons London and Cash.

According to, Slash wants a judge to rule they never legally married back in 2001, because Perla was still technically married to Carlos Marty, with whom she tied the knot with in 1993. They split up after a month and she got a divorce but it was discovered years later the forms to get a final divorce judgment were not filed properly.

In 2009, Slash and Perla reportedly got a judge to finalise her divorce from Marty and make it retroactive to 1994.

However, the rocker claims her divorce was never finalised, meaning he was never married to her and as a consequence she shouldn't receive half of the earnings he made during their marriage, thought to total tens of millions of dollars.

According to the site, because they believed they were married, a judge can still treat them as such - even if there are some inaccuracies with documents.

Perla told TMZ last year (15) their split was amicable and she hopes their divorce can be smooth despite the fact they didn't sign a pre-nuptial agreement.

"I don't know how any of that's (the divorce) going to work, I know he's going to do the right thing for me and his children as I would do the right thing to him. Like I said, it's amicable so there's no bad blood, at least not yet!

"We had a really long-lasting, loving relationship for a long time, we're best friends, we're business partners and we just want to do what's best for our kids."

Slash previously filed for divorce from Perla in 2010 but they reconciled two months later and renewed their vows in 2011.
