Reality star Kim Kardashian, who turned 29 on Oct. 21, says she's starting to feel old. "I'm not going to lie, I woke up this morning feeling a little old!” Kardashian tells People. "It's my last year in my 20s."
Kim, who became an overnight celebrity when her sex tape was leaked in 2007, has a younger man to help ease her into her 30s. Kardashian's 24-year-old boyfriend, NFL star Reggie Bush, helped usher in her birthday.
"The first person to wish me a happy birthday was Reggie," she says. "He called so early this morning."
To celebrate her big day, Kardashian plans to party in L.A. with her sisters and girlfriends. Reggie is currently in Louisiana training with his team, the New Orleans Saints.
The voluptuous 5'2" Kardashian says she's the thinnest she has ever been, thanks to regular workouts and a healthy diet.
"I'm the skinniest I've ever been," she said. "I stepped on the scale, and it said I was 114 pounds. I always weighed 120, 125; I was shocked."
In addition to working out 3-5 times a week at the gym doing lots of cardio and light weight-lifting, Kim does lots of lower-body exercise to keep her thighs and butt toned.
"I tried the Atkins diet, the cabbage-soup diet, every ridiculous diet ever," says Kim. "I've lost a solid 10 pounds in a little more than a year. I feel like I'm in the best shape of my life."
Still Kardashian, who recently released a trio of workout DVDs called Fit in Your Jeans by Friday, insists true beauty comes from embracing your body shape--no matter what it is. "The most important thing is not to be shy — work with what you have," she says.
