The Scream star wed the Brit in May 2007, but they have separated after three years of marriage.
Campbell filed divorce papers in Los Angeles County Superior Court in June (10), citing irreconcilable differences. The divorce has not yet been finalised, reports TMZ.com.
A source tells the website, "They're still really close friends, and it was a very amicable divorce."
The brunette also specified she wants to block the court from awarding Light any spousal support.
The next hearing is scheduled for later this month (Dec10).
