Two of her sisters just had gorgeous babies and another sister’s got a little one on the way. Is it any wonder Kourtney Kardashian is thinking about about having another baby? Pregnancy can be contagious, after all.

The Keeping Up With the Kardashians star revealed the revelation on the reality show, much to the shock of her sisters, Kim and Khloe.

"So, I've been thinking about freezing my eggs,” she told her siblings.

The 38-year-old mom of three told her sisters she doesn’t want a baby right this minute, but is considering freezing her eggs as “insurance”, in case she wants to add to her family in the future.

Kourtney shares eight-year-old Mason, five-year-old Penelope and three-year-old Reign with her ex, Scott Disick, and isn’t ready to close the door on the possibility of welcoming another baby should she feel ready someday.

As Kim points out, Kourtney will be “pushing fifty” a decade from now, and conceiving at that point may not be as easy as she thinks. Kourtney suggests Janet Jackson as an example of someone who’s experiencing new motherhood at a later age, but Kim might actually be right on this one. Jackson’s really the exception, not the rule.

A recent study by New York University’s School of Medicine found media coverage of Hollywood pregnancies might mislead people about how easy it is to get pregnant after 40.

It’s not easy, but as Kourtney says, it does happen. Unfreezing her eggs a few years from now is an option for the reality TV star, and she’s certainly proven that she is a mama who is up for a challenge. (Remember when she pulled out her own baby on TV?)
