Hilary and Haylie Duff have largely avoided the scandals plaguing so many other young pop stars: No stories about stints in rehab, drunken driving arrests and shoplifting. No embarassing photos or sex tapes.

They tried to keep a low profile in their parents’ divorce, too, slipping quietly into a Harris County courtroom on Thursday as their mother, Susan Duff, asked that her husband be ordered to pay her living expenses while their divorce is pending.

Mother and daughters slipped down a back elevator in an attempt to avoid news photographers soon after Judge Thomas Stansbury ordered Bob Duff to pay $100,000 in temporary support — $20,000 a month for five months, beginning Jan. 15.

Stansbury, a retired family court judge from Fort Bend County appointed to hear the case, also ordered Bob Duff to pay $150,000 of his wife’s legal fees by Feb. 1, although he later suspended the order until a hearing set for next month to examine a prenuptial contract between Bob and Susan Duff.
