LeAnn Rimes is ready to rock her 30s -- and beyond.
Late last month, the country singer wrapped up a 30-day stint at a rehab facility to deal with stress and anxiety. And in her first interview since her completion of that program, Rimes, 30, tells the Boston Herald she enjoyed her time away.
"I've been in therapy my whole life," explained the Grammy winner. "I like going. I like being able to have that third-party input and someone to listen that has nothing to do with your life. Everyone has an opinion of how I am and how I should be, and now I'm focusing on how I want to be."
Insiders told Us Weekly that Rimes sought help as she obsessed over husband Eddie Cibrian's suspected wandering eye -- fueled by cyberbullying she's endured since her 2009 affair with then-married Cibrian. "LeAnn has had major insecurity issues since she first got together with Eddie," a source said.
"I think it's really hard to deal with Twitter and Facebook and all these social media outlets," Rimes told the Boston Herald. "And it's hard to take it day after day of reading and seeing things that someone you don't even know says about you. As much as you said you don't want it to penetrate, it does, because you're human."
The country singer (an industry veteran since age 13) turned 30 Aug. 30, an admitted she's happy to say goodbye to her 20s.
"I had some wonderful times in my 20s, but your 20s are hard," she said. "It was a lot of learning experiences ... and a lot were thrown at me publicly. I was ready to embrace 30."
Rimes is set to address her famous mistakes in a brand-new single, "What Have I Done?"
"I have felt like I've had a piece of tape over my mouth the last four years," said the star. "I wanted to start the next 30 years of my life on a great foot."
