Kate Hudson kicked off Halloween weekend with a biker-themed bash in LA on Thursday night. Kate and her girlfriends dressed as the "Daughters of Anarchy" with the actress's mom, Goldie Hawn, as their matriarch, and Kate shared a series of photos of the fun on Instagram. A sexy group shot was captioned, "Mother of Anarchy is taking her daughters to a little party.... #HappyHalloween," and another snap showed Kate posing with Peter Kim, the founder of Hudson Jeans. The women were all clad in sexy leather getups, though Kate was clearly comfortable showing the most skin; the actress, who has been keeping busy promoting her Fabletics activewear line, was understandably excited to show off the fruits of her gym labor.
Kate is famous for throwing an annual Halloween party that never fails to bring out a star-studded list; last year, her event was attended by Fergie, Josh Duhamel, and her former Glee star Lea Michele, and boasted a Game of Thrones theme. This year's Sons of Anarchy-inspired party is sure to garner lots of crazy looks; already, Katy Perry has showed up as a giant Flaming Hot Cheeto.
