LeAnn Rimes has a new album–Spitfire–and it runs the emotional gamut. The 30-year old country singer addresses some of the major life events she went through while writing the songs, including the depression she experienced after having an affair with her now-husband, Eddie Cibrian.

Rimes met Cibrian on the set of “Northern Lights” while he was still married to Brandi Glanville and the two fell in love, but that didn’t mean she didn’t feel guilty about it.

“I think I opened up the can of worms for myself by writing this record. There were a lot of things I didn’t even realize I was feeling…I needed to go somewhere and really process all of that stuff. I was feeling all these crazy emotions and feeling terrible about myself and was disgusted by myself and thought I was pathetic,” she said recently. Her song “Borrowed” is about the affair.

Rimes famously went through rehab last year to “develop and maintain coping mechanisms”. The star said she was stressed and was having trouble with Glanville, as the two of them have had a public battle after the affair. Now, however, she’s feeling good about her life.

“I’m the strongest I’ve ever been,” she says. “I’m the most honest with myself that I’ve ever been, I’m the most secure I’ve ever been about myself and my family, and I’m the most confident I’ve been in a really long time.”
