Lamar Odom is suing his children’s mother Liza Morales over visitation and support of their two kids.The LA Laker star filed a petition in Manhattan Supreme Court on November 5, asking a judge to to set a “parental access schedule” and “reasonable child support,” the New York Post is reporting.

Morales is fighting back, she told The Post that Lamar, who married Khloe Kardashian 14 months ago, “basically checked out as a father four years ago.”

Odom and Morales, who never married had three children. Their youngest Jayden, died from SIDS in 2006 when he was just six months-old. The couple’s relationship was already on the brink, but the tragic death tore them apart for good.

Morales learned of Lamar’s plans to marry Khloe via a text message where he said he wanted the kids to attend.
