British singer Amy Winehouse’s odd behavior continues, while her fans, family and friends grow increasingly worried. Pictures taken by the media clearly show her with white powder all over the inside of her nose. She came out of her home in London this week with the white residue clinging to her nostrils, climbed into a waiting car, and changed her pants in full view of onlookers, including paparazzi. Returning home later on, Winehouse couldn’t find her keys, and getting on her back, slid under the gate to her home head first to get in. Earlier this week, she claimed she doesn’t take drugs, and that a bag of white powder spotted in the trunk of her car contained the driver’s towels.
