Lily Allen controversially dressed up as Dr. Luke as she attended Kate Hudson's Halloween party in Pacific Palisades. The 29 year old singer showed off her back tattoo in her revealing outfit and she also had a plastic toy stethoscope around her neck. On the front of the outfit was a blue name tag which read: 'Dr. Luke, gynaecology department'. Lily wore her lilac hair in a bun tied with a scrunchie, and topped off her ensemble with red lipstick and winged black eyeliner. The costume references pop star Kesha's on going lawsuit with Dr. Luke which claims the music producer "sexually, physically, verbally and emotionally abused her over a period of 10 years".
