Dita Von Teese stunned onlookers when she arrived at the Chateau Marmont Tuesday night exuding old Hollywood glamour in a chic blue dress.
Wearing her hair in a low bun, the model-actress-author was "glowing and hard to miss," says a source. "She was with a very large group of people at a table where everyone chatted quietly. She was smiling and laughing with the group but [Von Teese] was always very proper, sitting up straight and her demeanor was very polished."
While greeting other guests, Von Teese noticed Kelly Osbourne arriving. The two exchanged a brief hello before the Fashion Police host and her friends pulled up a table to join Von Teese's party.
Throughout the evening, Osbourne laughed and chatted with her group of friends. Osbourne and one girlfriend played endlessly with their cell phones and seemed fascinated at whatever popped up on their screens.
Osbourne later Tweeted about her night out with Von Teese and crew.
