Paris Hilton is close to being administered an IV drip by prison doctors worried she's not eating enough - according to media reports. The socialite is currently serving time at the Century Regional Detention Center in Lynwood, California for a parole violation. During her time behind bars her weight has decreased dramatically, according to British newspaper The Sun. An insider at the jail tells the newspaper, "Staff became worried as she seems to be very thin with her bones poking out. She was also very weak and lethargic. "They threatened to put her on an intravenous drip to rehydrate her and give her some nourishment unless she started eating. She has since managed to get a little food down, but doctors are closely monitoring her." Kathy Hilton admits her daughter continues to struggle behind bars. She says, "She's never been alone... This is, as she calls it, a real time out." Paris is expected to be released for good behaviour on 25 June (07).
