Celebrities at Miu Miu Fall 2013 Fashion Show

January Jones, Zoe Saldana, and Renée Zellweger lent their Hollywood support at Miu Miu's Fall 2013 show in Paris today. January channeled her Mad Men character, Betty, when she dropped by the event in a retro hairdo and a Miu Miu ensemble. Meanwhile, Zoe and Renée sported black outfits and chatted with Rebecca Hall while sitting front row. Renée and Zoe have more in common than just their taste in designers since both women have previously dated Bradley Cooper.

It's a good thing that January is getting into the '60s spirit, as filming for Mad Men season six is still under way. Jon Hamm and John Slattery filmed scenes for the new season of Mad Men outside a hotel in LA yesterday while January was in the City of Light. Fans will be able to catch the show soon as a new Mad Men promo was released earlier this week, calling the April 7 premiere the "affair of the year."
