Kate Walsh hosts her annual spooktacular Halloween party at a private residence on Saturday night (October 29) in Los Feliz, Calif.
The 44-year-old Private Practice babe dressed up as Morticia Addams while some of party monsters dressed up as a shower and Dorothy of Oz‘s Tin Man and Scarecrow (with Dorothy shoved in a sack). Pictured below!
Kate installed a dance floor above her pool, built a cemetery in a backyard, and filled her hot tub up with severed body parts. The scary good Halloween treats were the perfect touch!
Moments before the party, which was DJed by Chris Masterson, Zachary Quinto tweeted, “I am fireworks on the fourth of july.”
Jonathan Bennett cleverly dressed up as Kate‘s TV character, Dr. Addison Montgomery! Kate‘s costar Sara Ramirez even wore a sexy vampire doctor costume!
