Harry Potter stars Daniel Radcliffe, Emma Watson and Rupert Grint admit that they have all tried their hand at stuff teens at their age do - drinking and smoking.
However, the only difference between them and a lot of other young stars, is that they maintain their squeaky clean image by being careful about not getting caught.
17-year old Watson, better known as the muggle-born witch Hermione Granger, says that unlike a lot of young stars, the trio didn't take their first smoke, or their first drink in 'the middle of London', but in the company of close pals.
"You are careful not to do it in the public eye. You have your first cigarette or first glass of alcohol in a safe environment with your close friends - or you choose to do it in a nightclub in the middle of London," The Sun quoted her, as saying.
Adds Rupert Grint, the on-screen Ron Weasley: "Because we are quite busy we do miss out, but getting drunk for the first time, we still have those kind of experiences."
Harry Potter star Daniel Radcliffe also admits that he like to party and have fun, but insists that he won't be going over the edge.
"It doesn't stop us from having a party once in a while. Parties are fine and fun, but what I enjoy are the acting and the work," he said.
The three were speaking before the launch of the fifth film Harry Potter And The Order Of The Phoenix.
The movie opens in theatres on July 13, about a week before the release of the seventh and final book in the series - Harry Potter and the Deathly Hallows.
