Kate Walsh Counterfiles for Divorce.

Private Practice star Kate Walsh has counterfiled for divorce - two weeks after her husband Alex Young submitted paperwork for a split.The couple's troubled relationship was made public earlier this month (Dec08) when 20th Century Fox executive Young began legal proceedings for a divorce, after just 15 months of marriage.But the star has now filed her own suit, alleging the relationship broke down due to irreconcilable differences on 17 November (08) - five days earlier than the date Young listed.The pair married in September 2007 in front of more than 100 guests, including several of Walsh's former Grey's Anatomy co-stars.
