Khloe Kardashian not pregnant -- report

Looks like Lamar Odom's dad wasn't right after all: A source close to Khloe Kardashian tells Us Weekly that the "Khloe & Lamar" star is not pregnant, despite Joe Odom telling RumorFix that he's about to be a proud grandpa.

"Can't say I'm not surprised. At least I can laugh about it," Khloe tweeted Tuesday (April 17) after the pregnancy rumor made the rounds. No word on whether the vague post was about Joe's potentially untrue overshare, but it's certainly a possibility.

Khloe's rep denies that the reality star is expecting her first child, though she and Lamar, who wed in 2009, have been trying to conceive.

"It's so hard. I never knew about ovulation and the limited amount of time that you have to get pregnant," Kardashian has said, according to Us Weekly. "We would love to have kids."
