Khloé Kardashian isn't the only member of her family facing weighty issues.
Big sis Kourtney Kardashian, 30, admits she's nervous about gaining too many pounds during pregnancy. "I weigh myself every day," she told us at the Kardashian Charity Knock Out event in L.A. earlier this week. "I've gained 26 pounds since getting pregnant, except I gained three pounds since yesterday."
Being eight months pregnant and understandably bigger than usual hasn't stopped the E! reality starlet from conquering a red carpet in heels. But it sounds like Monday's event could be Kourt's last until after she gives birth...
"Today I vowed that I was going to wear flats, and then last second, I threw on some heels," said Kourtney, showing off a pair of fluorescent pink pumps. "I can't wait to sit down already. It's hard carrying extra weight. I'm over the red carpet being pregnant."
But stepdad Bruce Jenner warned Kourt that the really hard part was yet to come.
"I have great confidence she will get through this—that baby will be born" Bruce said, adding that the same doctor who delivered Kourtney will be delivering her child. "But then the real tough stuff starts for her. You've got a little baby there for 24 hours a day, for the next 20 years!"
