During an interview with the June edition of Marie Claire magazine, the songstress explained that she is too busy to think about having children at the moment so won't start trying for a baby any time soon:

"I don't feel old enough to have kids. I know I am mature. But being responsible for another human?"

She also opened up about her relationship with Fisher, joking that he laughs at her awkwardness: "My husband calls me the queen of awkward moments. Anything that can be made awkward, I will make it awkward."

In the same interview, Underwood confessed that at the beginning of her rise to international fame she would experience panic attacks from all of the people and photographers vying for her attention every where she went.

Speaking in the June edition of Marie Claire magazine, the 'Blown Away' hitmaker explained that when she first rose to fame she was made to feel very nervous by the swarms of people that would surround her:

"At the beginning of my career, I used to have panic attacks. People were touching me, screaming -- it made me really nervous. In public, I just get nervous."

"It’s a physical reaction, feeling like the walls are closing in. The fans are great. It’s not their fault. I don’t ever want to come across as ungrateful. But on my end, it is hard for me to process. Because I am still just me."

She also opened up about her childhood and family life, admitting that she was never very close to her siblings as they were significantly older than her: "I'm not a mushy person at all. We were never a huggy family. Or a ''let's talk it out'' family. Technically I have siblings but they are quite a bit older than me -- I was the accident -- so I have the only-child syndrome going on."

"I'm a little more selfish, a little more independent, a little closed. I do wish I were softer. I wish I were able to form relationships better. But hey, I mean...I'm not a sociopath."

Also taking the stage for live mini-sets are the Pistol Annies, singer Luke Bryan (shown below), Hunter Hayes and Little Big Town. The ceremony is due to take place at Nashville's Bridgestone Arena on June 5 and it will be broadcast live on CMT.com from 8pm ET/PT.

Underwood, meanwhile, has been nominated in the Video of the Year ('Blown Away') and Female Video of the Year ('Two Black Cadillacs') categories. Taylor Swift is also in the running for two prizes and has been recognised in the Video of the Year ('We Are Never Ever Getting Back Together') and Female Video of the Year ('Begin Again') groups.

The country star's sound isn't wholly similar to the 'Kiss You' lads' mainstream pop styling, but it seems there might be a mutual respect between the pair.

Speaking to ITN News, US star Underwood said that whilst she isn't too familiar with the boys themselves, they are all over American media. She said:

"I don't know that much about them personally, but we see so much about them in the US - where they are and what they eat for lunch. Young ladies always find young men to love, I think that's what it's all about."

When asked about a potential collaboration, the country icon said:

"I don't know. I never have the opportunity to meet them, but you never know, if we all cross paths at one point or another."

The winner of the fourth season of American Idol, who has frequently discussed her faith and religion in her songs, revealed her liberal attitude to same-sex marriage in a frank interview with The Independent.

She said: "As a married person myself, I don't know what it's like to be told I can't marry somebody I love, and want to marry.

“I can't imagine how that must feel. I definitely think we should all have the right to love, and love publicly, the people that we want to love."

The 29-year-old, whose new album, ‘Blown Away,’ knocked Adele’s 21 off the top of the Billboard charts, also claimed that the non-denominational congregation she belongs to is just as open to the idea:

"Our church is gay friendly. Above all, God wanted us to love others. It's not about setting rules, or [saying] 'everyone has to be like me'.

“No. We're all different. That's what makes us special. We have to love each other and get on with each other. It's not up to me to judge anybody."
