Gwyneth Paltrow wore a one-shouldered Stella McCartney mini Thursday night for Coach's 70th anniversary celebration at Beijing's Iberia Center for Contemporary Arts with the company's president Reed Krakoff. She's the star of the leather goods company's ads overseas, and has attended many events with Coach over the last six months. This visit was apparently Gwyneth's first to the city. She tweeted, "On my way to Beijing for the first time. Any recommendations for food, sights, traditional medicine, etc.?" She apparently got her friend Mario Batali in on the event as well, as she shared a photo of the meal he created for the bash on her Twitter account. She also sweetly added to Mario, "Only thing missing is you. And some Peking duck. . ."

As part of the evening's entertainment, Gwyneth Paltrow got singing again and took the stage to perform three songs, one of which was Cee-Lo Green's expletive-filled hit. Gwyneth made the trek to China following a stop in Germany, where she wore a plunging green Elie Saab gown to attend the Bambi Awards.

The duo were famous for conversing over the social networking site with both of their handles referencing the other partner, but we'll have to wait and see if Demi changes her Twitter name, which is currently MrsKutcher.
