Daniel RadcliffeDaniel Radcliffe’s smoking habit is reportedly annoying his Harry Potter co-star on the set of their new film.

A source on the set of Harry Potter and the Half-Blood Prince told the Sun: “Daniel has recently been smoking up to 20 cigarettes a day.”

“Every time they call ‘Cut’, he lights up. It’s disgusting.”

“Friends and co-stars including Rupert Grint have been warning him about the dangers of smoking. But he doesn’t take any notice.”

“He’s been having late nights out with stars like Kevin Spacey and Stephen Fry and seems to have picked up bad habits from the luvvie set.”
