Walsh to marry in early September

Grey's Anatomy star Kate Walsh will marry her fiancé Alex Young over America's Labor Day weekend.

The couple became engaged after movie mogul Young proposed in May, and they plan to wed at the Ojai Valley Inn & Spa in California in a sunset ceremony.

Walsh will wear a custom-made Monique Lhuillier wedding dress.

Guests at the ceremony will include Walsh's Grey's Anatomy co-stars Katherine Heigl and Sara Ramirez, according to People.com.
