Kate Bosworth brought her boyfriend, Michael Polish, along last night for a private dinner at the Chanel shop on LA's Robertson Boulevard. Joining Kate were other chic stars, like Christina Hendricks and Cat Deeley, and fashionable young ladies Elle Fanning and Hailee Steinfeld. It was Kate and Michael's second high-style event of the week, after they attended the launch of Burberry Body with Rosie Huntington-Whiteley on Wednesday evening. Michael has been by Kate's side nonstop for the past couple months, and things seem to be very serious between them. Kate, who parted ways with ex Alexander Skarsgard earlier this year, has referred to Michael Polish as her "life partner". She told the UK Times earlier this month that Michael is, "a special one. There's nobody in the world I admire or respect more. When I look at him, it's not a crazy infatuation, it's more like we are each other's life partners."
