An animated Lindsay Lohan joined friends for dinner at New York's Beauty & Essex. The actress – who drank soda during her meal – was very cordial to fans who approached her table. Lohan has such a good time that, before she left, she kissed her waitress goodbye!
Ever the fashionista, Sarah Jessica Parker was having a business meeting at West Hollywood's Chateau Marmont, but still managed to look chic in her gray blazer, heels and light-blue skinny jeans. The actress was in a secluded section of the patio, and was joined by a male and female associate. Says an observer: "[She] had a confident and carefree air about her."
Though her Roseland Ballroom concert ended a bit early, Ke$ha wasn't quite ready to call it a night. Instead, the singer headed to N.Y. club Tenjune for an official afterparty, where she sipped Liquid Lightening cocktails and partied in VIP until 3 a.m. For much of the night, the pop star was seated atop a booth, chatting with a mystery man, though she also talked with Simon Rex.
