New York: Singer Amy Winehouse's alcohol addiction has reportedly worried her friends, who fear that she might get herself killed.
The 27-year-old who has previously been to rehab for her severe alcohol addiction has passed out thrice in last week after drinking vodka, reported a website.
"Her drinking is totally out of control. Amy is constantly out of control on vodka. She is rattling about at home in North London drinking herself into oblivion. Three times this week she has been so drunk she passed out," a friend said after Winehouse's European tour was scrapped.
The 'Stronger Than Me' singer has also been boycotted by boyfriend Reg Traviss, 34, as he has vowed that he will not see her when she is drunk.
