Kevin Federline, and his lawyer were scheduled to appear Thursday at an emergency hearing in family law court, Superior Court spokesman Allan Parachini said. It was not known what issue the 28-year-old aspiring rapper planned to raise, though the former couple are in a custody dispute over their two children.

His attorney, Mark Vincent Kaplan, did not return a call seeking comment.

The hearing comes amid increasingly bizarre behavior by Spears, which culminated with her reportedly checking into and out of two rehab centers in a week and shaving her head bald on Friday.
