Sorry dolls: There isn't another little Kardashian on the way.

Lamar Odom's father, Joe, may have told his son and daughter-in-law Khloe Kardashian were expecting their first child, but a source close to the 27-year-old reality star tells Us Weekly she's not pregnant.

"I got a little news," Joe Odom told RumorFix Tuesday. "I'm about ready to have a grandchild!"

Kardashian -- who wed NBA star Odom, 32, in 2009 after one month of dating -- has long been vocal about her desire to have a child and the struggles she's faced when 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. "We would love to have kids. "[But] when you have schedules such as ours, it's really hard to hit that mark. So it's frustrating, but definitely. I want to have kids."
