Harry Potter star Daniel Radcliffe has blasted reports he smoked marijuana at a party - and is considering launching legal action over the claims.

The actor was pictured in Britain's Daily Mirror newspaper on Friday apparently smoking a roll-up cigarette as a pal painted a comedy mustache on his face at a get-together with friends.

The newspaper alleged Radcliffe had been puffing pot at the bash - but he has denied the claims and is considering the possibility of legal action.

A representative for the star tells WENN, "We categorically deny the allegations regarding Daniel Radcliffe published in today's Daily Mirror. Daniel does smoke the occasional roll-up cigarette, but he was not doing anything more than this. We are considering our position and will be taking all necessary action in relation to such allegations."
