Lily Allen goes to pot

Lily Allen has been pictured smoking what appears to be a cannabis joint.

The 'Smile' singer was photographed at London's world famous Notting Hill Carnival on Monday (27.08.07) tooting on a large hand-rolled cigarette, similar in shape to a marijuana 'spliff'.

Shortly after the picture was taken, Lily - who had been drinking heavily for most of the day - passed out on the pavement outside The Cow pub and had to be helped to her unsteady feet by restaurant staff from Rosa's Dining Room.

After drinking several pints of water and strong coffee to sober up, the pop star was put by staff in a taxi which took her to her north London home.

A source said: "She was really getting into the spirit of the occasion hen she stumbled and didn't get back up.

"People were crowding around and taking pictures of her until the staff came to her rescue. They took her inside the restaurant to stop everyone staring at her."

Earlier in the day, Lily suffered further embarrassment when she had a pint of Guinness poured over her head.

The diminutive star jumped on stage during a performance by reggae star Bobby Kray and pushed him off stage so she could sing herself.

Bobby retaliated by throwing the stout drink over her, much to the delight of the jeering crowd, leaving Lily to sulk at the side of the stage.
