Country music superstar Carrie Underwood is opening up about everything from grappling with all that comes with fame and her personality to her marriage with husband Mike Fisher and what she wrote about herself in her high school yearbook, in the June issue of Marie Claire’s (on stands May 21st).

On her personality: “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.”

On anxiety: “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.”

On awkward moments: “My husband calls me the queen of awkward moments. Anything that can be made awkward, I will make it awkward.”

What she wrote in her high school yearbook: “You were supposed to say what you would be doing in 10 years, and I said, ‘I will be rich, famous, and married to a hot guy.’ I guess I should have added a few more things.”

On having kids: “I don’t feel old enough to have kids. I know I am mature. But being responsible for another human?”

My little sister is all grown up!!!!!

You might know her from “American Idol” or as Frida Romero on “Glee,” but over the years I’ve come to know Jessica Sanchez as my little sister or by nicknames like “boo thang” or “cray cray.”

I can say so many wonderful things about her, but the one thing I love most about her is that she’s still the same genuinely sweet, hardworking, and grateful girl she always has been. The only thing different about Jessica now? She keeps getting more and more talented and more and more people know who she is… Including savvy New York paparazzi!

Music, of course, is her #1 passion. But, she also has a passion for fashion! We spent Mother’s Day afternoon shopping in SoHo (and thanks to Google Alerts I found these cute pictures from our fun filled day around town!). You wouldn’t believe the eye she has already for style at only 17-years-old. For the readers out there that love the Jessica Sanchez signature style, she scored BIG at Catharine Malandrino, 7 For All Mankind, 3NY and TOPSHOP.

Purchase Jessica Sanchez  Me, You & The Music on iTunes and watch her debut music video for “Tonight” featuring Ne-Yo…after the jump!

Kyle Richards is one busy woman!

She is a doting wife, mom to four, likable reality television star, successful store owner and proud philanthropist — and yet she balances it all so well, thanks to multitasking, healthy AND smart eating (she loves fresh veggies from the farmers market!) and hitting the gym hard!

“I’m picking up my kids from school while I am talking to you, was at the store this morning…got my nails done first… I am always go go go go,” Richards told me. But as active as she is, keeping her body in shape, she says, “isn’t easy.” She commits to power yoga once a week and circuit training the rest of the week.

As much as Kyle Richards enjoys her busy life, she is greatly looking forward to “doing absolutely nothing” on Mother’s Day  on June 12th: “I like to do as little as possible. I just like to sleep in and have someone else make the breakfast.” For Father’s Day, however, it’s the total opposite this year. While normally she encourages husband Mauricio to play golf, this year they will be spending in Aspen, Colorado hiking and, Kyle insists, shopping: “That’s the only way to get to me to go. We can ride our bikes to shop.”

All sorts of celebrities flocked to Churchill Downs to celebrate the 139th running of the Kentucky Derby, where Orb took the win.

Lance Bass, Lauren Conrad, Jason Biggs, Tiki Barber, Scottie Pippin, Kid Rock, Krysten Ritter, Joey Fatone, Miranda Lambert, Star Jones, Jason Biggs, Jenny Mollen, Christian Siriano, Carson Kressley, Jai Rodriguez and supermodel Coco Rocha were among the stars who walked the red carpet and signed a 6-liter bottle of Moet & Chandon Imperial for the brand’s ‘Sign for the Roses’ philanthropic initiative, which raises money for the Churchill Downs foundation.

Though it was pouring down rain, the celebrity attendees stayed dry on the tent covered red carpet, which provided shelter from storm.

Jennifer Hudson and Tom Brady were spotted in Millionaire’s Row but neither decided to walk the red carpet.

After the jump, celebrities sound off on their Kentucky Derby first experiences and fashion!

Are Justin Bieber and Selena Gomez back together? Who’s coming to the defense of Gwyneth Paltrow? Why has “Jersey Shore” star Ronnie Ortiz-Magro had to put the fist pumping and smushing on hold? And Taylor Swift bought a $17.75 million home…in cash?
