Carrying her on-again boyfriend Scott Disick's baby, Kourtney Kardashian told Ryan Seacrest in an interview for his KIIS-FM radio show on Thursday, August 13 that she actually never planned to become pregnant. "This probably sounds so dumb, but there's so many times I'll forget to take my pill and I don't think it's that big of a deal," she said. "It's just so stupid."

On how Scott responded the news, Kourtney shared to Ryan, "He was way more excited than I was." She continued, "He definitely wasn't as nervous or scared [as I was, but] then I think once I was fine with it, then he gets scared."

Asked about how her pregnancy affects her fashion style now that she is about five months along, the reality TV star revealed, "I just wear jeans and keep them unbuttoned and wear a big shirt." Kourtney, furthermore, said she is still brainstorming names for either a baby boy or girl.

Going public with her pregnancy on Wednesday, August 12, it wasn't until the following day that Kourtney Kardashian revealed the identity of her baby's father. During an appearance on the "TODAY" show she outed that the baby daddy is "Scott [Disick], my ex-boyfriend ... who is now my boyfriend." Kourtney is expected to give birth around Christmas.
