The New York newspaper Daily News said Wednesday the troubled recording artist had suffered a nervous breakdown, while TMZ.com reported McCready had entered an Arizona rehabilitation center after allegedly mixing vodka and Ambien in an apparent suicide attempt.

Usmagazine.com said McCready went to rehab after being treated for an emergency visit to a Nashville hospital.

"Mindy McCready did receive emergency care at Vanderbilt University Medical Center," the singer's representative told Usmagazine.com. "Other issues made it prudent for her to seek longer term and broader based treatment. ... To her credit, she has entered into an extended care facility where she will receive the care needed and for the moment we ask that everyone respect her privacy."

McCready was jailed last year for five months for violating her probation in a 2004 drug case.
