LeAnn Rimes is 30, and ready to get back to what she does best ... make music!

The stunning country songstress opened up about her recent treatment for stress and anxiety, her relationship with Eddie Cibrian and the inspiration behind her latest single "Borrowed" off her upcoming album Spitfire.

Rimes admits to Leno that the song is about her very public affair with now-husband Eddie Cibrian. Watch her talk about her recent treatment below.

And not only did she sing her heart out, but she kicked off her shoes for one number!

LeAnn Rimes performed a mix of holiday songs, old singles and songs from her upcoming album at An Evening with LeAnn Rimes at the Las Vegas Hotel last night, and as always, she gave it her all. We do love a good holiday tune, but we're most excited about her new EP, Spitfire, which will be released in April. Not just for the music, but the lyrics ... you know she's got a lot to say these days!

LeAnn Rimes and Eddie Cibrian attended the NOH8 4th Anniversary Party at the Avalon in Hollywood last night, and the duo snuggled up on the red carpet before she took the stage to perform a few songs.

LeAnn and Eddie have both posed for the NOH8 campaign in the past, which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

“It just breaks my heart seeing kids committing suicide because they're not accepted. It kills me,” Rimes told gay weekly Pride Source when she posed for her second NOH8 shoot this summer. Glad to see her stepping out for a good cause ... and rocking a sexy little black outfit while doing it!

Even when she's wearing sweats, she looks great! Of course, we want to steal her white Lululemon zip-up, so we might be a little bit biased...

On Wednesday LeAnn Rimes was spotted gassing up her Range Rover in Studio City, and while she kept it casual and skimped on the makeup, the country crooner will be glamming it up tonight for her appearance at The Avalon in Hollywood for the NOH8 4 year anniversary bash.

So what's the latest in her ongoing feud with hubby Eddie Cibrian's ex-wife Brandi Glanville? While LeAnn has been keeping her cool lately, she did tweet earlier this afternoon, "Hey, twitter....if I've blocked people STOP showing their tweets in my timeline!! #annoyingtwitterproblems." Maybe she should just take a break from the social networking site until all this blows over?

LeAnn Rimes is on top of the world with her new album Spitfire coming out, a sexy body and a loving family, but the 30-year-old songstress now has babies on the brain.

While sitting down with E!'s Giuliana Rancic, the stunning country singer said the following about wanting a baby with hubby Eddie Cibrian:

"I would love to be a mom. Eddie and I talk about having kids and I would love to be a mom. I didn't ever want to bring a child into the world without taking care of myself. And that was another reason I decided to go (into treatment)."

Aside from discussing baby plans, LeAnn talks about her recent treatment, as well as her new album. Just recently, Rimes released two new singles "What Have I Done" and "Borrowed."

The full interview with Giuliana airs this Sunday.

The Cibrians are heading to Washington!

Sexy songstress LeAnn Rimes led the way at LAX with hubby Eddie, and sons Mason and Jake, in tow. Looks like the boys are having a blast!

The fashionista rocked a Balmain studded leather jacket, cutoff denim shorts by One Teaspoon, Feel The Peace sweater, American Apparel tights and Valentino black boots while making her way through the terminal. We can't help but notice that Givenchy bag sitting on her suitcase, too. Loves it!

LeAnn is playing a show tonight in Washington to promote her upcoming album Spitfire. Her two new singles "What Have I Done" and "Borrowed" have already hit the radio.

After hearing both songs, we're dying to hear the rest of the new album!

LeAnn Rimes is getting emotional and singing from the heart with her latest single "What Have I Done.'

When asked about the meaning behind the new track, Rimes said the following:

"What Have I Done is an apology. This whole album is the truth, but at no one else's expense but mine. WHID is for those who's ever broken anyone's heart and I think we've all been there, at some point, in one way shape or form."

This is the first single off the country songstress' upcoming album Spitfire which is due out next Spring.

Can this family be any cuter?!

Eddie Cibrian and his stunning wifey LeAnn Rimes channeled Olivia Newton John and John Travolta in sexy Grease costumes.

As for the boys, it was all about G.I. Joe and the Navy Seals. Adorbs!

We love how they went all out for Halloween. No doubt, this Sandra Dee is one fierce Spitfire.
