Others at the bash included Ewan McGregor, 12 Years A Slave actor Chiwetel Ejiofor, Hollywood star Hudson, Arctic Monkeys rocker Alex Turner and his ex-girlfriend, TV presenter Alexa Chung, small screen funnyman James Corden, and supermodels Karlie Kloss, Suki Waterhouse and Lara Stone.

The event also included performances by 1980s pop stars Spandau Ballet and producer Mark Ronson.
