One day after her 30th birthday, LeAnn Rimes has checked into an in-patient facility to cope with anxiety and stress…

The country superstar voluntarily checked into the 30-day treatment facility to address emotional issues, LeAnn’s rep confirms to People.com.

“This is just a time for me to emotionally check out for a second and take care of myself and come back in 30 days as the best 30-year-old woman I can be,” LeAnn says.

Her rep ensures LeAnn’s treatment is not for an eating disorder or substance abuse, despite LeAnn’s being a victim of body bullying in the past.

“All the things in my life will be there when I get out, but you know what? I’m hoping they’re not going to affect me as much,” LeAnn says. “I’ll have the tools to know how to deal with them.”

Eddie Cibrian, LeAnn’s actor husband of one year, calls his wife “the most remarkable and courageous woman I know” and gives full support to LeAnn.

The rehabilitation facility has granted LeAnn permission to keep her weekend tour obligations in September. “She will report back [to the facility] each weekend,” her rep confirms.

LeAnn will release a new album, Spitfire, and embark on a new tour this fall.
