Liam Gallagher was ejected of a bar

Liam Gallagher was kicked out of a London bar, this weekend!

The former Oasis rocker, who is 41 years old, was seen at The Holly Bush in Hampstead, North London, according to UK newspaper the Sunday People.

Liam was 'behaving strangely' before he got into an argument with the bartender over his tab.

A source said: 'He was making a real nuisance of himself even before he got kicked out'.

"He was acting irrationally and started kicking off and swearing after the barman told him he hadn't paid for his drinks. He took exception to what the barman had said and started giving it the big I am, like <I'm famous!>"

Liam was heading to the bathroom at around 11 p.m. The bouncer suspected the rocker is doing drugs and banned him from the bar entirely.

'He accused him of snorting cocaine off the toilet seat and said there was still some left on the seat even after he came out', the insider said.

'Apparently Liam hadn't even bothered locking the door. Liam wasn't happy about being thrown out. The bouncer told him <you're barred> and he was like <are you joking?> It was embarrassing to watch'.

Liam's spokesperson declined to comment. Liam has faced legal troubles in the past due to drugs-related issues.

In 2009, however, he said he had not taken drugs for nearly a year and was determined to remain clean for his children.

Liam shares a a teenage-daughter with singer Lisa Moorish and sons, age 12 and 14, with actress Patsy Kensit. He also has a 15-month-old daughter with journalist Liza Ghorbani.
