MediaTakeOut.com is reporting that Khloe Kardashian was rushed to the hospital for an “unspecified gynecological problem.” Khloe and Lamar have been trying  to get pregnant for a long time, and it looks like they've run into another barrier. Her sister Kim even skipped out on an appearance for their clothing store DASH to be with her sister. Khloe’s hubby Lamar Odom has also taken a leave from the Dallas Mavericks. Both caught the first available flight back to Los Angeles yesterday.

An insider who is very close to the family didn't give out any specifics, but says it's SERIOUS!

We're praying for you Khloe!
