Kate Hudson in Custody Battle with Ex Chris Robinson Over Son Ryder

Kate Hudson and her ex husband Chris Robinson are in a new custody battle over their 12-year-old son Ryder.

The Black Crowes singer has filed to re-open the custody agreement he and Kate settled upon after their 2007 divorce, E! News reports.

Kate and Chris divorced back in 2007 after seven years, where they settled on a joint custody agreement of their then two-year-old son Ryder.

In the re-opened case, Kate and Chris have agreed that an evaluator from the court will perform a child custody evaluation, and make recommendations for developing a parenting plan that addresses legal and physical custody, including where Ryder will reside.
