Paris Hilton was arrested early Thursday after police observed her driving erratically. According to an officer of the LAPD the hotel heiress was arrested at around 12:30 a.m. in Hollywood, after she failed a sobriety test at the scene. Paris who was traveling with her friend Kimberley Stewart, could get three months’ probation and be ordered to enter an alcohol program and have her license restricted for 90 days if found guilty of the offence. Paris was picked up from the station by her sister Nicky and her boyfriend. Paris’ spokesperson has confirmed the arrest and say that at the time she was pulled over Paris was driving home from a charity event where she had one margarita, after spending the entire day shooting a music video for the next single from album. The whole situation was “probably the result of an empty stomach and working all day and being fatigued.” And who says being an `it girl’ is an easy life?
