Just one day after her 30th birthday, LeAnn Rimes checked herself in to an in-patient treatment facility on Wednesday (Aug. 29), seeking help for anxiety and stress.

"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," the singer tells People. "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."

While LeAnn doesn't specifically reveal the sources of her stress, she has weathered her fair share of public backlash in the past three years, mainly due to her admitted affair with now-husband Eddie Cibrian, while both were still married to their first spouses. She has also had to defend her slim frame, as tabloids continually splash photos of her in swimsuits and accuse her of having an eating disorder -- something she vehemently denies. But when The Boot spoke to LeAnn last year, she seemed to have gotten past the media scrutiny.

"I've learned from my mistakes and have a great life. I am really happy," she told us. "You go through hiccups in your life where you make choices that are not necessarily the right ones, and everyone sees it. It became so obsessive because everyone thought they had me pegged, that I could never do anything wrong. But I'm human! I understand the obsession, but I don't agree with it. It's way over. Time to move on."

More recently, the singer has found herself in perhaps the most heated of her many, infamous Twitter wars, even getting her lawyer involved. Earlier this month, LeAnn called former fan Kimberly Smiley to confront her about what she deemed to be mean and derogatory remarks the northern California mother and teacher had posted on the social networking site. Smiley recorded portions of their conversation without LeAnn's consent, which is against the law in California.

LeAnn's rep, Marcel Pariseau, won't reveal whether the potential lawsuit -- or anything else, for that matter -- is what pushed LeAnn to seek treatment. But he does insist she does not have substance abuse problems, nor an eating disorder.

"She is simply there to learn and develop coping mechanisms," he tells People. "While privacy isn't expected, it's certainly appreciated."

The star will be able to leave treatment for her already-scheduled concerts. "The facility has granted her permission to keep her weekend tour obligations, as LeAnn doesn't want to disappoint her fans," says Pariseau. "She will report back after each weekend."
