Britney Spears' new lawyer has a tip for Kevin Federline: If you're going to ask for your legal bills to be paid, don't leave a $2,000 tip for the waiter on a $365 check.

Attorney Stacy Phillips, who recently took over Spears' case, told a court Monday that the pop star has already spent more than $1 million on her child-custody case and objects to paying nearly a half-million dollars in legal fees for her ex-husband, who has enough money to have recently left the exorbitant gratuity.

Phillips had asked for the hearing to challenge a move by Federline's lead lawyer, Mark Vincent Kaplan, to have Spears pay his legal bills. Commissioner Scott Gordon did not rule during the hearing, part of which was held behind closed doors. Superior Court spokesman Allan Parachini said the decision may be made Tuesday.

Federline has sole custody of his two little boys by Spears, who is under the conservatorship of her father, James, following bizarre behavior and two hospitalizations. Federline and James Spears chatted amiably at court.
