Amy Winehouse was rushed to hospital and put on a drip on Wednesday night, her dad Mitch has admitted.
The Sun newspaper says she was checked into a London clinic under a fake-name after suffering from dehydration caused by her withdrawal from crack.
Wino has been in rehab finally trying to get off drugs and get her career back on track. A source told The Sun: Amy was looking very pale and thin. She looked ropey and exhausted.
