Harry Potter actor Daniel Radcliffe has "categorically" denied newspaper allegations that he was photographed smoking cannabis.
The Daily Mirror published photos believed to be of the star, taken by a fellow reveller at a London party.
"Daniel does smoke the occasional roll-up cigarette, but he was not doing anything more than this," said a spokeswoman for the 20-year-old actor.
Radcliffe is currently filming the last two parts of the Harry Potter series.
"We categorically deny the allegations regarding Daniel Radcliffe published in today's Daily Mirror," the spokeswoman said.
"We are considering our position and will be taking all necessary action in relation to such allegations," she added.
