Kate Hudson and Stella McCartney Stay in Vogue Together

Kate Hudson joined best friend Stella McCartney for a chat at today's Vogue Festival in London. The two-day event kicked off today, and other major stars in the fashion industry like Tom Ford, Rachel Zoe, and Diane von Furstenberg are expected to attend as well. This afternoon, Stella and Kate joined UK designers Matthew Williamson, Mark Fast, and Christopher Bailey.

Kate returned to the UK on Tuesday with her youngest son, Bingham Bellamy, following a stay on the West Coast. Last Friday, Stella and her dad, Paul McCartney, hosted a bash for their famous friends like Gwyneth Paltrow and Gwen Stefani at LA's Madeo. Kate had a party of her own this week — her 33rd birthday was yesterday, and we marked the milestone with a look back at Kate Hudson's hottest bikini moments.
