LeAnn Rimes is getting back to what she knows best: music.
Just eight days after the 30-year-old country crooner checked into treatment for anxiety and stress, Rimes was back on stage, performing for fans Friday night at the Eau Claire Regional Arts Center in Eau Claire, Wisconsin.
"I'm totally cool and so happy. I think I'm about to cry," the singer told the crowd, according to People. "Thanks for being awesome fans…patient and understanding."
And Rimes got even more open with fans as the show went on.
The Northern Lights star, who recently sued two women for allegedly recording a private telephone conversation, told fans, "I'm pissed off at a lot of things, and I just can't say it. So, it comes out in the music."
During the 70-minute concert, Rimes mentioned that her album is set to be released next year, and performed some of the new tracks on it, including a song called "Borrowed," which included the lyrics, "I don't want to give you back. You're the best I've ever had."
Rimes called the ballad "the most honest song I've written," according to the mag.
Following the show, Rimes headed to Twitter to show her appreciation to concert attendees.
"Thanks to all my wonderful fans in Wisconsin," Rimes tweeted Friday night. "You showed me an amazing amount of love and respect tonight. Love you always."
Rimes told the audience she will return to treatment after her shows this weekend.
