Clean-cut Harry Potter star Daniel Radcliffe has been photographed allegedly smoking a marijuana joint at a party in London.
The Daily Mirror newspaper splashed the photos across the front page of its edition on Friday, saying the pictures were taken by fellow partygoer Wadia Tazi.
The British actor has since issued a statement denying he smoked marijuana at the party.
But Tazi said he did not initially recognise the world-famous 20-year-old actor who, he said, told partygoers: "I love weed".
"Daniel looked spaced out and away with the fairies," Tazi told the newspaper.
"I was surprised by his behaviour.
"He is a kids' favourite. I'm not sure what his fans will make of it.
"At one point, a girl dragged him away, saying: 'Come on Daniel, follow me. You don't trust me, do you?' She pulled him into the toilet and started drawing a huge comedy beard on his face."
A spokeswoman for Daniel Radcliffe says he "categorically denies" the Mirror's allegation that he smoked marijuana.
"Daniel does smoke the occasional roll-up cigarette, but he was not doing anything more than this," the spokeswoman said.
"We are considering our position and will be taking all necessary action in relation to such allegations."
