Kate Walsh Formally Seeks Divorce From Alex Young

Looks like Kate Walsh's short-lived marriage may have been falling apart even sooner than thought - by a couple of days, anyway.

A little less than two weeks after her husband filed for divorce, the Private Practice cast member submitted her own paperwork asking for a permanent split from 20th Century Fox movie executive Alex Young.

Both parties cite irreconcilable differences as the reason their 15-month union ended so soon, but while Young's filing listed their date of separation as November 22, Walsh's counter-filing has the break coming five days earlier.

Not in question is the fact that the duo tied the knot September 1, 2007, in front of more 100 guests and some of Walsh's former Grey's Anatomy co-stars.

There has been speculation that David Sutcliffe, who plays SWAT team officer Kevin Nelson on Private Practice, may have played some sort of role (however indirect) in the couple's split, but that's all it is - speculation.
