Country bombshell Miranda Lambert has revealed that now she has turned 30, her attitude still remains as feisty as ever but she feels as though she has calmed down. 

Speaking exclusively about her fiery nature to People Country magazine, she explained that now she has established herself as a singer-songwriter, she can settle back down into herself:

"That attitude brought me here and got me where I am. But that was me in my 20s. The chip on my shoulder is gone. At some point, you calm down. I'm happy. I'm more settled. I've put down roots. I feel like people have accepted me for who I am, with all the craziness, loudness and fire."

The 'Mama's Broken Heart' sensation also opened up about her marriage to Blake Shelton, admitting that people like to spread rumours about their relationship in the press: "There were rumours that it was about our marriage, that it had become boring and predictable. How do people even think that up?"

"It's not easy when everyone is trying to tear you down, but you make a commitment and you stick to it. In other parts of the entertainment world, it sometimes seems like marriage is so disposable. But country has some enduring marriages - Johnny and June, George and Nancy, Faith and Tim. I'm thankful we have those role models. I feel like our peers are rooting for us. They're holding us up."

Lambert, meanwhile, recently earned herself an incredible 7 nominations for the upcoming Academy of Country Music Awards and the event is due to take place on Sunday, April 6 at the MGM Grand Garden Arena in Las Vegas, Nevada. Taylor Swift is up for 5 prizes.
