LeAnn Rimes has admitted herself to a rehabilitation center to cope with stress, her rep says:

    "LeAnn has voluntarily entered a 30-day in-patient treatment facility to cope with anxiety and stress. While there will be speculation regarding her treatment, she is simply there to learn and develop coping mechanisms."

Rimes herself issues a statement:

    "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. 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 ... I'll have the tools to know how to deal with them."

LeAnn and her husband Eddie Cibrian renewed their vows in April after celebrating their first year of marriage and Rimes celebrated her 30th birthday just two days ago.
