They announced their split two months ago, and now they’re making it official: George Lopez’s wife Ann filed for divorce in Los Angeles Superior Court.
Citing irreconcilable differences, Ann Serrano Lopez is seeking spousal support and primary custody of their daughter, Mayan, 14, with visitation for George, according to the petition filed Tuesday.
The couple had been married for more than 17 years.
In 2005, Ann famously donated her kidney to her husband. Crediting her for giving him life, George, 49, told PEOPLE at the time, “I can’t pay her back, but what I can do is make her as happy as she thought I would when we first got married.”
