According to recent reports, Amy Winehouse may have been diagnosed as having brain damage from her drug use.? An insider told the UK's Sun that in addition to her crystal meth binges, the singer's 36-hour marijuana marathon caused symptoms similar to those associated with schizophrenia. Winehouse had allegedly overdosed two times, once in August 07 and then in July 08, causing hallucinations and multiple personality traits. With Labor Day weekend rocking super shopping sales, Hollywood's best were sure to line-up to dish-out their hard-earned dollars on Monday. Alongside friends, Rhianna stopped by Gucci on Rodeo Drive before grabbing a bite at Cafe Med. Hillary Duff paraded around Los Angeles all alone to buy some of her favorite must-haves from Urban Outfitters and a Beverly Hills giftshop. Plus, Cameron Diaz shopped at Barney's in the Home of the Rich and the Famous. And one of the most talked-about shopping sprees included Ashley Tisdale and her boy-toy of the moment. They jetted over to the Beverly Center to grab some kicks at Steve Madden. And some questionable shopping happened over the weekend with Lindsay Lohan. She wasn't missing work or ditching the gym to hit the stores, but this 22-year-old definitely did a No-No when she failed to show-up to her grandpa?s Long Island funeral.? Instead, Lohan opted to chill and sho with a guy friend in Soho. That's it for celeb news for now. I'm Dana Ward and we?ll see you next time on GetTheDaily.com. Distributed by Tubemogul.
