Amy Winehouse `downs vodka on way to rehab`

The former addict was apparently spotted downing a bottle of vodka on her way to rehab.

According to The Sun, she bought a miniature of Smirnoff from a corner shop in North London and downed it at the counter.

An onlooker told the newspaper, 'She seemed out of it. She was stumbling about, slurring her words.

'I was shocked to see her buy vodka so early in the day, and even more shocked to see her knock it straight back.'

And just minutes before, the troubled star allegedly marched into a hair salon and demanded to use the toilet before throwing up in it.

One customer said she heard the 27-year-old tell staff, 'I just puked all over your bathroom.'

A second client said, 'I felt really sorry for the staff. I think they were too scared to say anything.'

However, Amy's spokesman denied she had been sick, saying her comment was a joke. He added, 'Amy's embarked on treatment at The Priory.'
