Amy Winehouse allegedly attacked two men during a drug-fueled night out.

The singer is facing arrest after she reportedly head-butted a guy who had
hailed her a cab outside a London bar, just hours after punching her alleged
other victim in the face.

The married star is also said to have kissed a mystery man and was seen
smoking illegal drugs in the street.

Trouble began on Tuesday evening (04/22/08) when Amy and a group of pals
arrived at a pub in Camden after spending the afternoon drinking in her
home.

Once inside, she allegedly hit Moroccan musician Mustapha el Mounmi after he
refused to give up his space on the pool table.

Mustapha – who had a bruised eye and swollen lip - said: “I feel so angry.

She smashed my face hard. I could not hit back – she’s a woman.”

Amy then returned to her flat but later went to nearby bar Bar Tok in the
early hours of yesterday morning (04/23/08).

An onlooker said: “She was off her face, throwing drinks around and turning
over tables. Amy screamed, ‘I am a legend, get these people out. I want to
take drugs.’ ”

After kissing her mystery man, Amy left the bar and outside a man tried to
get her a taxi so she could get home safely.

However, she reportedly thought he was trying to molest her so head-butted
him.

A source revealed to Britain’s The Sun newspaper: “The guy said she was a
snarling tigress. It’s believed she caused a serious amount of damage.”

The man reported Amy to police, who have now begun an investigation.

If convicted of assault, the 24-year-old singer – whose husband Blake
Fielder-Civil is currently in prison awaiting charges of grievous bodily
harm (GBH) and conspiracy to pervert the course of justice – could face a
jail sentence and a $4,000 fine.
