Kris Jenner may have spilled the beans about her daughters' alleged pregnancies.

While Kim Kardashian has revealed she's expecting a baby girl via surrogate with her husband Kanye West, both Khloe Kardashian and Kylie Jenner are rumored to be pregnant right now -- but neither woman has publicly confirmed or denied the news.

Kris, however, recently posted a photo of nine sets of children's pajamas on Instagram, six of which were labeled with her grandchildren's names. That left three bundles of PJs that were not labeled, so the picture sent fans into a frenzy thinking they're for the babies on the way.

"Thank you so much #burtsbeesbaby @burtsbeesbaby #bbbfamjams for the most amazing collection of family jammies ever and i am obsessed with the plaid !!!!!" Kris, 62, captioned the photo.

The labeled names that are visible are Dream, 1; Saint, almost 2; Reign, almost 3; Penelope, 5; and Mason, almost 8. North, 4, likely has her name on one more set, so that would leave a set for Kim's baby, as well as Khloe and Kylie's alleged children.

"Can't wait to cuddle up with the kids #holidayseason," added the Keeping Up with the Kardashians star. "Thank you for a collection for every one of my grandchildren #blessed #grateful"

Kylie, 20, is reportedly expecting a baby girl with her boyfriend Travis Scott, a rapper, early next year.

Meanwhile, Khloe, 33, will reportedly welcome a son with boyfriend Tristan Thompson, an Ohio-based NBA player, around the same time.

Once news of Kylie's pregnancy surfaced, a source told People that Kris was "shocked."

"It definitely took some getting used to," the source said, especially considering Kylie is her youngest daughter.

"But Kylie has always been very headstrong, she's always wanted to do her own thing despite what Kris says. Of course Kris just wants the best for her daughter and loves and supports her no matter what."
