People is reporting that “Grey’s Anatomy” star Kate Walsh will marry her own McDreamy, Alex Young, over Labor Day weekend!

It will be a 3-day event at the Ojai Valley Inn & Spa, a resort two hours north of Los Angeles.

Walsh, 39, will reportedly wear a custom-made Monique Lhuillier gown, and co-stars Katherine Heigl and Sara Ramirez are on the guest list.

The “Private Practice” star and film producer Young aren’t wasting any time – they got engaged just four months ago!
