In what is being referred to as her most candid interview ever, Carrie Underwood graces the October 26th issue of 'PEOPLE' magazine and dishes on the pressures of balancing her marriage to Mike Fisher with a successful career with a new baby.

"You feel guilty about every single thing, every decision you make, everything you do," she tells the magazine. The country star, who gave birth to son Isaiah Michael Fisher in February, also opened up about breastfeeding, noting that she plans to nurse her baby “as long as I can take it."

"It’s hard," the co-host of the 2015 Country Music Association Awards added. "My supply is pretty nil. We have to supplement with formula. I’m doing the best I can, you know?”

The Grammy winner also admits that she never saw marriage or motherhood as her future. "I never dreamt of my wedding day and the perfect guy," she says. "Then I met Mike, and I was like, ‘Wow, so now I know what I was missing.’ And the same with my son. I was never like, ‘I want kids so bad.’ And now that I have Isaiah in my life, I’m like, ‘What did I do before?’"

Underwood's brand new studio album, 'Storyteller', will be released on Friday, October 23rd.

Beauty can be timeless!!! At 50 years old, Sandra Bullock has been chosen as the World's Most Beautiful Woman Of 2015 by People magazine, but even she admits that learning she captured the annual honor made her laugh out loud.

"No, really. I just said, 'That's ridiculous,' " the Oscar winner tells the publication.

In fact, beauty to her doesn't involve a person's physical appearance. "Real beauty is quiet. Especially in this town, it's just so hard not to say, 'Oh, I need to look like that'. No, be a good person, be a good mom, do a good job with the lunch, let someone cut in front of you who looks like they're in a bigger hurry. The people I find most beautiful are the ones who aren't trying."

Other beauties featured on the annual list include Ariana Grande, Gabrielle Union, Vanessa Hudgens, Taraji P. Henson, Jenna Dewan-Tatum, Laverne Cox, GiGi Hadid and more.

After some personal struggles, Britney Spears has spent the past few years reclaiming her life and admits in the April 6th issue of People magazine, which she covers with her sons Sean Preston and Jayden James, that she is finally in a really good place.

"I'm the happiest I’ve ever been," Spears, 33, tells the publication in this week's cover story, where she also talks about Charlie Ebersol, her producer boyfriend of six months.

While she admits that her two boys are her top priority, the 33-year-old singer is also gearing up to release her new music. "Pretty Girls", her new single with rapper Iggy Azalea, is slated to premiere on May 5th with a music video and hopefully, an album, set to follow. Exciting news!

Chris Hemsworth, our reigning Most Beautiful Man, added yet another coveted title to his resume yesterday when he was named Sexiest Man Alive by PEOPLE magazine.

"I think you've bought me a couple of weeks of bragging rights around the house," the Australian-bred hunk tells the publication for this week's cover story. "I can just say to her (wife Elsa Pataky), 'Now remember, this is what the people think, so I don't need to do the dishes anymore, I don't need to change nappies. I'm above that. I've made it now.' "

Idris Elba, Chris Pratt, Matt Bomer, Bradley Cooper, Scott Foley and Jamie Dornan are among the other studs featured on the list. The issue hits newsstands on Friday, November 21st.
