With the holidays in full swing, Kristen Stewart seem lonelier now than ever.

The Twilight star looked down in the dumps as she celebrated Thanksgiving a day late with her dad, step-mom and brother. Although she broke up with then-boyfriend Robert Pattinson months ago, she doesn't seem to have fully recuperated. In fact, Kristen seems to be regressing.

"Kristen looked depressed," an X17 photographer on the scene observed. "She spend the holiday with her family, but you could tell something was missing. She looked alone and lonely."

As usual, she dressed down for the post-Thanksgiving dinner. Kristen wore a white Mr. Science S**t tee with skinny jeans, styled with a blue Mercenaries cap. Her father and brother sported matching grunge looks; the casual fashion style must run in the family.

Relatives and friends later dropped by KStew's dad's Sherman Oaks pad. When Kristen left the party to return home, she seemed as gloomy as the Los Angeles weather.

"When Kristen went home alone, in the rain, she just seemed sad," our photographer said. "Her holiday wasn't complete without Rob."
