Paul McCartney and his estranged wife, Heather Mills McCartney, appeared in London's High Court on Thursday for a preliminary hearing in their divorce case.
Mills McCartney, 38, said nothing as she arrived at the courthouse for the closed door session. The 64-year-old former Beatle arrived at the court's backdoor soon after.
McCartney whistled and snapped his fingers as he left the building after the two-hour hearing, flashing a peace sign to photographers stationed outside the court's parking lot before being driven off in a waiting car.
Mills McCartney left through a backdoor about 30 minutes later.
The couple separated last May after four years of marriage and began divorce proceedings in July. They have a 3-year-old daughter, Beatrice.
British law forbids publishing details of allegations in divorce cases. Mills McCartney began legal action against a number of media outlets after disparaging claims about her husband, alleged to have been contained in divorce court papers drawn up on her behalf, were reported in the press.
