The roller coaster last few years that it's been for LeAnn Rimes seems to continue.  From the love triangle that she found herself in, to her divorce and eventual remarriage, it's been a crazy last few years. 

However, now it appears that LeAnn can't cope with the stress of her life and has checked herself into a rehab center to deal with it.  Reps for LeAnn just released a statement  to People.com saying, "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 also issued a statement herself ... saying, "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."
