Kate Walsh has plenty of reasons to celebrate this week.
ABC announced that she'll star in a "Grey's Anatomy" spinoff in the fall, and the 39-year-old actress told Us Weekly magazine Tuesday that she's engaged.
"It happened a few days ago," Walsh said of her engagement to Alex Young, a studio executive. "I'm on cloud nine."
People magazine reported Wednesday that Young proposed in San Francisco.
"Private Practice" takes her "Grey's Anatomy" character, Dr. Addison Shepherd, from Seattle and moves her to Los Angeles. There she reconnects with a friend whose medical practice needs an obstetrician — and with the friend's former husband and business partner.
