Kate Hudson arrived at LAX with sons Ryder and Bingham yesterday and this morning they touched down in Paris. While Kate was in LA, she attended the amfAR Inspiration Gala and posed on the carpet in a sexy red Prabal Gurung gown. Inside the event, she partied with Katy Perry and Sarah Jessica Parker. Kate's social evening came during a break from her work on the HBO movie Clear History. She's been in Boston working on the project with Eva Mendes and Jon Hamm, who has since moved on to start filming the next season of Mad Men.
