A month before she is expected to birth to the baby in her womb, Kourtney Kardashian gushes about her growing belly, telling Life and Style in an exclusive interview, "I run around naked all day at home!" Revealing more of her love for her physical appearance, she says "I'm totally excited to gain weight, and I'm embracing it ... I like that my body is changing. It's a beautiful thing."

Telling the magazine that her pregnancy actually wasn't "expected or planned," Kourtney raves she has mixed feeling about becoming first-time a mother. "My pregnancy has been wonderful. I love being pregnant. I'm excited to be a mom -- but I'm nervous," she confesses.

In fact, her boyfriend Scott Disick, who fathers her upcoming baby, has been acting very supportive. "Scott and I have been going to different parenting classes," Kourtney tells Life and Style. "They made me nervous at first, putting all kinds of information into my head, but they're helpful. They're a fun thing for Scott and me to do together."

About to become a mother, nevertheless, doesn't tickle the 30-year-old reality star to walk down the aisle with 26-year-old Scott any time soon. "I'm 30, but I never was that girl who was like, 'I need to get married'," she says. "I never had a plan. Now I have so much to think about for the baby. I'll worry about myself later."

Kourtney Kardashian confirmed in early August that she is pregnant with on-and-off boyfriend Scott Disick's baby. She, however, waited until last month to publicly announce that the upcoming baby will be a boy. She is due to give birth on Christmas.
