Hollywood film-maker Brian Grazer has split from his wife, novelist GIGI LEVANGIE-GRAZER after eight years of marriage. The producer, 54, filed for legal separation from Levangie-Grazer in Los Angeles Superior Court on Monday (17APR06), citing "irreconcilable differences". Grazer, who has produced movie hits including A Beautiful Mind, Cinderella Man, 8 MILE, LIAR LIAR and MY GIRL, is seeking joint custody of the couple's sons PATRICK, 2 and THOMAS, 6. Levangie-Grazer wrote the screenplay for the 1998 movie STEPMOM, starring Susan Sarandon and Julia Roberts.
