Kate Winslet headed to Shanghai, where she attended two events for the Swiss watch brand Longines yesterday. She wore an LBD in the afternoon for a photo call and then changed into a royal blue gown for a gala celebrating the launch of the DolceVita jewelry watch. Kate is a Longines "ambassador of elegance," along with other stars like Aishwarya Rai Bachchan, Andre Agassi, and Steffi Graf, and has appeared in ads for the company. Kate's stay in Asia may be brief, as her services may be required to promote Carnage at NYC's Lincoln Center Film Festival. The picture has its premiere this evening. Kate's rumored new love interest Ned Rocknroll hasn't appeared to have accompanied her on her travels, though. He and Kate were publicly seen together recently at a memorial service in London held for Ned's uncle, Richard Branson's late father.
