Washington, Sept 11 (ANI): Paris Hilton's mum Kathy Hilton has claimed that her celeb daughter is extremely hardworking.

The socialite's mum said that her daughter works so hard that she has to remind her to take a break.

"Paris works so hard. I always say, Paris, you also have to stop now and again and smell the roses," Contactmusic quoted Kathy Hilton, as telling German newspaper 'Die Wielt'.

In the interview to the publication, she also said that the Simple Life star's case was mishandled, for no one was punished the way she was.

"You simply don't get behind the wheel when you have even had just a bit to drink. That is totally irresponsible. I agree with that. I do criticise how Paris' case was handled though," she said..

"That was not about the law, the prosecutor even admitted that. His own wife drove twice without a licence and even smashed up a car. No, of 2000 cases that were like Paris', no one was punished like she was," Kathy added.

Kathy also refuted claims that Paris is a spoiled brat and insisted that she has always been a 'tough mother'.

"When Paris disobeyed us, we would first confiscate her mobile phone - practically her life. Second time it would be disconnected, for a month or so. Mothers are mothers, annoying. Perhaps I was too strict with Paris," she said.

"She was cheeky but never spoiled like it's always written...we never sued and so this myth grew larger and larger."

"I am very strict. I call my daughter up and say, 'That is enough now, stop, I don't want to hear any more. You better stay home.'"

"Of course I worry. That is why I nag just like all mothers." (ANI)
