OTRC: Mindy McCready's ex claims she's 'pushing her luck' by keeping her son

Billy McKnight, ex-boyfriend of Mindy McCready's and father to the 5-year-old son in the middle of a custody battle between McCready and her mother, thinks the country singer is "pushing her luck" with authorities.

During an appearance on "The Today Show" McKnight said, "I think she believes she has a case and doesn't realize she's pushing her luck on this one."

He added that he did have a chance to speak to his son. "He did sound healthy and ok. He wasn't crying or scared," McKnight said.

McCready, a country singer who hit it big during the 1990s, violated a custody agreement in Florida when she took her son out of the state and brought him to Tennessee on November 29. McCready's mother, Gayle Inge, was awarded guardianship of Zander in 2007 following McCready's trouble with the law.

A Florida judge gave McCready until December 1 to return the boy to Inge but McCready said she was not going to return her son because she is in Nashville, Tennessee, and cannot travel due to the fact that she is nearly seven months pregnant with twins. The singer also claimed her son suffered abuse at her mother's house. Inge denied the abuse allegations.

"Once the child is located, we will pick him up and bring him back to Florida," Terri Durdaller, a spokeswoman for the Florida Department of Children and Families told the Associated Press. "Although these circumstances are unfortunate for a young child, his safety and well-being are our number one priority."

McCready also provided a series of emails to the wire service with Lee County Judge James Seals' ruling to return the boy and correspondence with her attorney. Seals wrote to McCready's lawyer, "Mom has violated the court's custody order and we are simply restoring the child back into our custody."

"The court makes no judgment about whether Mom will or will not competently care for the child while in her custody. It only wants the child back where the court placed him," Seal's statement read.

The 36-year-old singer has dealt with domestic abuse, drug and DUI arrests as well as a suicide attempt since the mid-1990s, after she released her double platinum debut album "Ten Thousand Angels" in 1996.

She was arrested in 2007 for getting into a fight with her mother and resisting arrest. In 2008, McCready was admitted to a Nashville hospital for a suicide attempt after police said she cut her wrists and took several pills. McCready appeared on the third season "Celebrity Rehab" in 2010.

"It is a giant whirlwind of chaos all the time," she told the wire service about her past. "I call my life a beautiful mess and organized chaos. It's just always been like that. My entire life, things have been attracted to me and vice versa that turn into chaotic nightmares or I create the chaos myself. I think that's really the life of a celebrity, of a big, huge, giant personality."
