Mindy McCready will voluntarily surrender to authorities Tuesday to serve 60 days in a Tennessee jail for a probation violation, her rep tells PEOPLE exclusively.
The country singer, 32, was arrested for violating her probation for prescription drug fraud in June.
"I am working very hard to put all of this behind me as quickly as possible so I can get back to what I like to do most: sing, write songs, and entertain," said McCready in a statement Monday morning.
The troubled singer had entered rehab July 16 for undisclosed reasons
and she was previously jailed in 2007 after violating probation on a 2004 drug arrest.
McCready also said in the statement: "I would like to thank my fans for their unwavering support as I continue to work on my recovery and to regain custody of my precious son, Zander."
