Jack Osbourne has been criticised by an anti-drink driving charity for branding Mischa Barton's DUI arrest "no big deal".
Osbourne made the comments following the actress' arrest for driving under the influence on 27 December (08) in West Hollywood.
He said of Barton's misdemeanour, "Everyone gets DUIs... but you only hear about it when celebrities get them. It is a big deal but it's not a big deal, just a slap on the wrist."
But U.S. group Mothers Against Drunk Driving (MADD) insist celebrities must act more responsibly - and that alcohol-related arrests must not be promoted as "a rite of passage".
Chuck Hurley, of MADD, tells New York gossip column, "Drunk driving is not a rite of passage but it does seem as though some high profile celebrities in Hollywood and in professional sports think it is... (it) kills about 13,500 people a year and injures thousands of others, even though it is completely preventable."
