Baby siblings misbehaving is nothing new and it seems Paris Hilton's little brother Baron is no exception.

The other heir to the Hilton fortune was arrested in Malibu on Tuesday morning and charged with DUI. Following in the precarious footsteps of her big sister, the 18 year old was pulled over by police in his black Mercedes and blew a blood alcohol reading of 0.14 - twice the legal limit.

There are also reports that just before his arrest, Baron 'bumped into' an attendant at a nearby service station.

Not only is Baron in hot water for driving under the influence he has also a case to answer for drinking alcohol 3 years before he reaches the legal drinking age of 21 in the US.
