Caitlyn Jenner revealed that one of her kids is expecting a child but didn’t share which one.

While visiting The Toy Store in Quincy, Calif., Thursday, the gubernatorial hopeful opened up about her 18 grandkids and joked she wanted 30 for the evenness of the number before confirming she’ll soon have 19 grandchildren, as one is “in the oven,” TMZ reported.

Although the former “I Am Cait” star, 71, didn’t share which daughter or son’s spouse is expecting — she has six kids — there have been rumors swirling that Kylie Jenner is pregnant with her second child.

Internet sleuths have been noticing that not only did 24-year-old Kylie not share any photos of herself from her birthday party, her friends and family also didn’t post pictures of her. They also noticed that all birthday tributes to the Kylie Cosmetics founder posted on Instagram were old photos of her.

Eagled-eyed fans also have been pointing out that Kylie’s elaborate nails on her grid posts haven’t been the same as her Instagram Stories, furthering the rumors that she’s pregnant and posting pictures from various periods of time.

A rep for Kylie didn’t immediately return Page Six’s request for comment.

The youngest “Keeping Up With the Kardashians” star shares 3-year-old daughter Stormi Webster with Travis Scott.

Rumors began to swirl that Kylie and the rapper, 30, had reignited their on-again, off-again romance when they traveled to New York City with their daughter in June to walk the red carpet as a family at the Parsons benefit, where Scott was being honored.

Caitlyn shares sons Burt, Brandon and Brody and daughters Cassandra, Kylie and Kendall with exes Chrystie Scott, Linda Thompson and Kris Jenner. She’s also a stepparent to Kourtney, Kim, Khloé and Rob Kardashian.
