Celebrity news website Radaronline.com Thursday published excerpts of an audiotape of Gibson telling Oksana Grigorieva, the famous director is battling in court, that the way she is dressed made her look like a “pig in heat.” Attorneys for Gibson and his ex-girlfriend have concluded a closed-door hearing with a judge handling their child custody case.

Attorneys for Gibson and Grigorieva declined to comment on the case, which remains sealed. The couple split in April. Gibson’s attorney, Stephen Kolodny, says the former couple entered into a confidential agreement a month later. A child custody case was filed in Los Angeles last month, but those records are sealed.
