McCready took the boy during a recent visit at her father's southwest Florida home and a judge signed an order Thursday ordering authorities to take the boy into custody and return him.
"I'm doing all this to protect Zander, not stay out of trouble," McCready wrote in an email to The Associated Press Thursday. "I don't think I should be in trouble for protecting my son in the first place." McCready says she is in Tennessee and it is looking less likely that she will bring her son back to Florida. She says she cannot travel because she's nearly seven months pregnant with twins.
McCready and her mother have had a long custody battle over the boy.
Until recently, the boy was living with McCready's mother, who was awarded guardianship in 2007.
McCready says her son has suffered abuse at her mother's house; her mother, Gayle Inge, denies the abuse allegations.
Since topping the country charts in the mid-1990s, the 36-year-old singer's life has been filled with domestic abuse, drug and DUI arrests and a suicide attempt. McCready also fought the release of a tape in which she reportedly talked about former Yankees pitcher Roger Clemens, with whom she had an affair as a teenager.
