La Clipper Lamar Odom failed to turn up in a New York courtroom Friday for a custody hearing with ex-girlfriend Liza Morales because of a back injury. Odom, the husband of reality-TV star and “The X Factor USA” co-host Khloe Kardashian, could not make it to the hearing after he injured his tailbone during a game and was advised not to travel. Instead, he called into the hearing via phone. Odom has taken Morales to court to set a “parental access schedule” over their children, 12-year-old daughter Destiny and 9-year-old Lamar Jr. The athlete reportedly wanted to adjust his custody deal with Morales so he could have the children appear on his E! reality spinoff show with Kardashian, “Khloe and Lamar.” A source tells us that “Odom filed a petition to establish time sharing of the kids and agree on finances and child support.” Odom and Morales were never married. He married Kardashian in 2009 after they dating her for a month. Howard Michael Rudolph, Odom’s attorney, told us that “Lamar loves his children and was in court to resolve the details of time sharing and finances.” Liza said in a 2010 interview with Star that she was opposed to the children’s being filmed because “Lamar has always been welcome to see the children but he hardly comes.” She and Odom had a third child, Jayden, who died from sudden infant death syndrome when he was 6 months old.
